Controversial Color Theory: RYB vs CMY Color Wheel - What are the REAL Primary Colors?

[@SarahRenaeClark]

So… what’s your verdict? What caught you by surprise?

[@heminadias5025]

I am still in shock that we can make red with magenta and yellow!!

[@mpetersen6]

And magenta is red and blue in the correct ratio with red being the dominant color in the mix. There actually is no specific wavelength of light that corresponds to magenta. The whole field of color theory and the primary color wheel is based on the fact that a light souce when shined through a prism and split into its constituent wavelengths. If the red, yellow and blue are then shined through a second prism they will not split into other colors. Its basic physics and optics. Wishing that magenta and cyan are actual primaries will not make it so. But in the world of color mixing yes it is possible to consider them as such and use them. But really you are just using a mix of the true primaries to get the magenta and cyan. Note this is only true for the actual wavelengths of the primary colors. If we take the reddish portion on the spectrum we will wind up with some blue and yellow. I'll put my virtual soapbox away for now.

[@snakedaemongaming6590]

I've known this for the longest time

[@snakedaemongaming6590]

Sorry didn't finish writing my comment I was always taught with the cmy as primary, this was due to my uncle being an artist for years and between him and my step father being a photographer They would often argue over it

[@snakedaemongaming6590]

Sorry 1 more point to add Although I was taught this from a young age, it actually doesn't mean much to me, I'm slightly colour blind, I don't understand colour at all

[@harukastorm4]

I'm an advocate for teaching the CMY colorwheel in school. It's mostly because here in Germany (where I'm from) we learn the color wheel with watercolor and the teachers tell us to only use red, blue and yellow. Therefore all students always end up with muddy purple. But when you ask the teacher why that is, they always tell you that you have to had made a mistake. And it discourages a lot of kids from making art, because they think that they can't make it right, when the actual mistake was the color choice from the teacher. It's just heartbreaking to see young children get frustrated about art and often even quit it completely. Thats not only my experience - every one I talk to about this has the same experience.

[@SarahRenaeClark]

I think it’s a shame that some art teachers aren’t aware of the more complex sides of color. I don’t expect kids to be taught CMY in primary school, but it would be beneficial for teachers to at least understand what they are teaching and how/why colors mix the way they do

[@harukastorm4]

The way we were taught the RBY colorwheel was also with very specific shades of red and blue. So it wouldn't make a difference changing them to magenta and cyan other that you could mix way more vibrant colors.

[@jesterparty6947]

Actually she right the problem is she didn't teach you about temperature. Most blues used in school are cool tones while most reds used in school are warm tones. Thus making a muddy purple what you teacher should have done was talk about split palettes on how colors come in more then one tone.

[@MusicalRaichu]

@@jesterparty6947 in my school we used a cool red and warmer blue, so a bit closer to cmy, which broadened the gamut a bit. but greens still turned out yucky. but alas my teacher told me it was my fault for not mixing properly, not because it was impossible to get vivid colours by mixing only three primaries.

[@qwmx]

It gets worse when society leave untrained hypocritical teachers to teach art. My year 6 teacher (this is in Australia) used this art idea textbook and told everyone in the class to ONLY use two colours JUST like the picture in the textbook (she even pointed at the areas of the picture) but the one kid that was away on that day, came to class the next day, got told to make the artwork and she made it with rainbow colours and the teacher showed it off, as if like what she did was a masterpiece. The teacher was right, it was beautiful BUT, the teacher herself emphasised to everyone that we're only allowed to use TWO colours (just like the text book), so we had our creativity quashed because we're worried about pissing off a psychotic teacher and the one kid who had no idea what happened, she ended up looking like the most creative kid in class LOL.

[@thefrugalcrafter]

I like to use a split primary palette where you use a warm and cool version of each primary. I have. Notices that cool colors are more transparent and mix with less mud.

[@SarahRenaeClark]

That’s another approach that I was thinking of bringing into this video, but I’ll save it for a video specific to color mixing. I like it too, but I haven’t used it much personally!

[@Gwenluvsmusic]

I was coming to the comment section to say similar.

[@justacatwhocantype]

Agreed. I find that for traditional media, a split primary is definitely the best solution.

[@justtheletterV274]

Well split primary is exactly like a CMY but with a cool yellow instead of green. And the cool and warm blue. Now, personally, violet blues are cool and cyans are warm but that is a matter of opinion. They’re both cool colors (duh, they’re blues) and when you mix Cyan and magenta, you get a violet blue. This violet blue’s hues can be either French Ultramarine (PB29), Indanthrone Blue (PB60), Ultramarine Violet Blue (PV15 BS), or Cobalt Blue Deep (PB72). Meanwhile, for Cyan, Phthalocyanine Blue Yellow Shade (PB15:3), Phthalocyanine Turquoise (PB16), or Manganese Blue (PB33). Note these are all hue choices, there’s no right or wrong choice. Also, if you mix neutral yellow w/ Cyan or magenta, you get the warmer and cooler versions. Warm Red by Cool Red and Yellow and Cool Blue by Warm Blue + Cool Red (since Turquoise = Tropical Sea and Indigo = Early Night Sky). Credit: SoulKeever

Another factor that isn't talked so much about is that magenta and cyan are fairly recent colors, coming from the era of synthetic dyes, and even now the very bright ones are only available as dyes (like ink in printers or makers), not pigments (like watercolor, oil and pretty much all other traditional art media). So when historical color theories were created, cyan and magenta weren't actually available.

That depends on the color system, in the substractive color model (CMY) white is a primary color.

In CMY, the primaries are Cyan, Magenta and Yellow. White is “not” a primary. In fact, white is never a primary color.

Primary colors is a color setup where there you mix to make new colors. A setup that you choose set up either own youre own or where you buy your paint.

White is technically not a color, so there's your answer right there. It's a shade, much like black, to lighten or darken actual colors/hues. Obviously this is only correct when talking about pigments, light is a whole other discussion. Think of black and white like the brightness setting on a monitor.

[@snowpuppies1]

Sarah, this is probably the best explanation and summary of color theory I’ve seen. You did a marvelous job of explaining how the main models came about, their strengths and weaknesses, and the science behind it all without getting too technical, but still getting the point across. I was honestly ready to throw out the traditional color wheel altogether, but your points about teaching children (and non-artistically inclined folks) about general color mixing are very well put. I do think, however, that at least cmy should be introduced much earlier than it is, and probably rgb as well.

[@SarahRenaeClark]

Thank you. And yes, I agree!

In high school physics, a 3-bladed fan is often used to demonstrate RGB. When each blade is covered with a primary color and the fan is started, you see white light. Which, of course, cannot be duplicated with pigments. Thank you Sir Isaac.

[@keylimepie3143]

Issue was that from what I observed at least, this stuff was taught in a Physics 2 class, which isn't required, and a lot of folks get deterred from Physics 1 which deals with Kinematics, the stuff like acceleration, forces, energy, friction, etc. As a result, very few decide to continue on to Physics 2 which covers the stuff like electricity, magnetism, and light.

[@magentamonster]

@@keylimepie3143 I think teaching kids about light early on would be a good idea since it's particularly interesting due to the connection to colours. The Physics 2 stuff seem more interesting than the Physics 1 stuff. After all, electricity and magnetism seem like magic. Perhaps that's actually why they teach them later though, they think they're too hard to understand because they seem like magic. But students are also likely to be more interested in them. Does the education system even consider what students are interested in as a factor? Because if they don't, that's a shame. They need to consider interest as well as difficulty and importance. Boring subject matter can turn students off. Teaching the interesting subject matter first might even make the otherwise boring subject matter more interesting, just because the students will be more interested in the subject.

[@staciamarie8458]

I can’t wait to share this with my senior high art students!! It came up one day in class as a bit of an aside and I sort of threw out the idea that RBY aren’t the only “primary colours” and they all looked at me like I had 3 heads LOL.

[@marlenelieb5935]

I remember having to draw a grey rectangle for art theory in woodsculpting school. The catch was we had to do it with a red, a blue and a yellow pencil. It was next to impossible to get it to be actually grey because the pencils weren't CMY. But I still did learn a lot in that class. Nonetheless it's always good to remind oneself about color theory is really helpful to just have that in the back of your head.

[@kayturs]

Theoretically, CMY makes the most sense as subtractive primaries. Cyan only absorbs red light. Magenta only absorbs green light. You mix the two and you get a color that absorbs red and green, and so you're left with blue light reflecting back. On the other hand, you simply can't make cyan with RYB. Red absorbs green and blue, yellow absorbs blue, blue absorbs red and green. What combination of these can be mixed to absorb only red? If you think about it, it's impossible That's why in theory CMY works best for subtractive colors. Each color only absorbs one primary color of light, and so it has the most flexibility to construct any ratio of R:G:B

[@nickytembo4112]

And the color schemes are better too

[@MusicalRaichu]

you can get the same hue as cyan by mixing blue and yellow. it just won't be as saturated so it won't look vivid.

[@leonardodeangelis4403]

Yes, it is the same thing I thought, but this works best only in the theory (as you said). In real life it is really hard to create perfect pigments that when mixed together block 100% of the white spectrum they receive. Most of the times there are unwanted subcolours that arise when the pigments are mixed that lead to the appearance of dark tints. I'm not able to explain this super well in 3 lines, but there is another super clear and useful video that does this much better than me (kzbin.info/www/bejne/a4uXYmqegpKFd6M).

[@JNCressey]

> "absorbs only red light" light isn't just made up of red light, green light, and blue light. it's a spectrum. yellow light, orange light, and red-orange light all exist and would be absorbed at various amounts by the cyan pigment. two different pigments could appear to be the same exact cyan when under daylight, but then look different to eachother when under a different kind of light-source.

Now I have a better idea. Thanks 👍

[@ThatOneLadyOverHere]

I actually teach my kids cyan and magenta along side blue and red because the common way to use these words has you percieving cyan as a light blue, but it isn't and magenta as a light red, but it isn't. Separating them helps you understand how the colors work better.

[@Bmonkeygurl]

Good discussion of a complex topic. As both a traditional artist and someone who has a degree in photographic technology, I am annoyed that this discussion doesn't come up more. I shifted myself to cmy ages ago because of how we worked in the darkroom on color photography correction. But even I recognize that it isn't a perfect system and some flexibility is involved. I just wish more elementary school teachers would start exposing their kids to the various systems and elements. I have had some good lively discussions with the art teacher on our campus. 😉

As a former journalist/sub-editor working in print media, my colour choices are heavily influenced by the CMYK colour theory, although I also believe that Sir isaac Newton's (light prism theory) Colour Wheel is a very useful tool for beginner colourists to see "how" colours work in harmonies etc. ETA: Trying to remember what I was taught in art at secondary school, pretty sure we did do work using both the RYB colour wheel and the CMY one though back in the 1980s in the UK.

[@Naturally-Bright]

Even though I'm someone who adores the cmy color wheel and have my beef with the ryb wheel, I think it wouldn't be a bad idea to teach both to students. But instead of it being the idea of "RYB for children, CMY for teens and up", it could instead be explained as "If you don't have access to Cyan and Magenta, Blue and Red is alternate option" since cyan and magenta are harder to find in certain mediums. Of course, there's more nuance than that to color, but honestly I think it'd be easier for kids to grasp color theory and colors in general if they were taught this from the start. Wonderful video!

I've learned the CMYK years ago, but as a personal stylist and image consultant I had to "unlearn" (most) of the CMY system since it doesn't totally work for this field, and traditional RBY works the best for analizing people's skin color, undertone and their best colors Need to add that my work consists on analizing the content/ balance of primary colors within any color, especially neutrals (brown, beige, even grey).

Very well spoken! I come from a music background which also has theories and wheels and as a musician you learn to link it all, sharps, flats, letters, and kinds (natural, blues, harmonic, etc). also as a Kid I learned that mixing colors of light gets you a different result from mixing colors of paint. all this together and I'm boggled why someone would saythere is 1 color wheel, and you are using the wrong one.

[@MusicalRaichu]

many artists these days recommend six primaries, warm and cool varieties of R, Y and B, in addition to black and white. how you divide colours is partly perceptual, partly cultural. in Greece, they don't call the sky blue, they call it galazio = azure. while they have a specific word for orange, they usually classify shades of orange as either red or yellow. they call mauve anything between violet and magenta.

I believe there is likely more to color behavior on the wave length than we realize. We have harmonics and octaves and such with sound waves perhaps light behaves in the same way and we just cant see the bridge that connects blue back to red as wave length gets smaller, but our brain already has those colors.

@@rytheguy1800, Those would be the ultraviolet parts of hydrogen's spectrum called the Lyman series. The lens of the eye is responsible for filtering out UV light, but the retina can see ultraviolet. I think one of your lenses is letting a bit of UV through. Ultraviolet would look similar to the hues around magenta because the L-cones have a secondary peak in their sensitivity around ultaviolet, so the UV stimulates S-cones and L-cones more than M-cones. The artist Claude Monet had a lens removed because of cataracts. The hues in his later paintings are considered to be because of UV vision.

I haven't seen a mention of the YURMBY wheel in your video or post, which is growing more popular among artists (especially realist painters and fantasy illustrators). It's based on 6 primaries, but you're never trying to mix them all at once. It's used in conjunction with the gamut mask to create atmospheric, more natural looking color palettes. At the center of your gamut is your neutral color, and depending on the shape of your gamut a "neutral" may actually be a warm or a cool color (not a gray) because colors are relative. This way of thinking about color can really shift our art. I recommend the book "Color and Light" by James Gurney which has taught me more about color in art than any other book or course (and I've taught graphic design so my knowledge of color theory was already pretty solid).

[@SarahRenaeClark]

I haven’t actually heard of the YURMBY wheel- but I’ve just looked it up and it looks fantastic! Also like the split-primary palette (which I also didn’t talk about) this looks to use 6 main colors instead of 3, which I think is a much better approach for artists. I think I’ll do a future video aimed at color mixing and will explore both wheels, as they both offer a far bigger variety of colors than any 3 set of primaries. Thanks for the recommendations!

[@NelaDunato]

On a different note, I don't really see the point of using any 3 primary color system in art. CMYK and RGB are limited because of their industrial use, but there's never a reason to stick with such a limited selection of pigments in art. Just because some color can be mixed, doesn't mean it should. Teaching kids that you can mix with CMYK? Yeah, let's do that in one lesson and then drop it. Color harmonies work better based on the 6 color wheel. Painting palettes limited to any number of "primaries"? Completely unnecessary. Everyone picks their own favorite pigments based on the subject matter they draw or paint.

[@NelaDunato]

@@SarahRenaeClark I'm glad, you're very welcome! :) I was writing my follow up comment at the same time and yes basically I agree that 3 color system is unnecessarily ascetic for art. 6 colors are better for sure, but still it's pretty arbitrary. When it comes to choosing pigments for a limited palette, I'm following the guideline: "Which colors need to be the most saturated? Get that as a single pigment, mix the rest." So I don't use lemon yellow at all (primary cool yellow), but I have a really nice green gold watercolor which is a tertiary color in most systems. Also no portrait palette is complete without one brown!

As an art teacher, I teach traditional rby, cmy and rgb as color models. I can't stand people who discredit the rby model without knowing how it came to be and how it's a valid color model as much as cmy and rgb. No color model is perfect. And each are useable and useful to their own extent. Also a common problem that most students face is that cyan and magenta pigments and paint are not always readily accessible in stores as compared to red and blue paint.

[@SarahRenaeClark]

Yes! I actually found it incredibly hard to track down a proper magenta in multiple mediums, even just for the simple example I wanted to show in this video. Even paints called “magenta” were not a true magenta.

The basic issue is: how our eyes see color. Then adding what the color is made of and that influence. What alters the entire scope is 1) every eye is different, 2) light & chemicals vary in behavior.

I absolutely loved this video! Is so amazing and educational. I was actually taught CMY at school like 20 years ago back in Spain, but I do recognize RYB as primaries and I loved to see the bigger picture on this video

[@quranbyeasha]

Thanks Sarah, this was SO helpful! I've always followed the RYB colorwheel, but I was never really pleased with the results of mixing. And I just realized that the CMY colorwheel exists, and I think that it is going to solve all of my problems. But I haven't tried it yet, this is just what I think...

[@CrimsonStigmata]

When I went to art school we used gauche to create our color wheel for our design classes. Using the RYB Color wheel. We had to make shades and tints too. It was pretty challenging but fun. I learned about cmyk in my Graphic design classes. In our painting classes which used oil paints we used a typical colors like raw sienna, brunt umber etc to make our colors.

There are more various hues that can be used to describe cyan. Cyan can be either closer to green or closer to blue. It can be used to describe any blue-green color like turquoise, teal, aqua, etc. There is also a wide range of colors used to describe Magenta. It can either be closer to reddish-pink or it can be closer to purple. I still believe kids should be taught the difference between cyan and blue. They are quite different from each other.

[@user-od6ue9zv9u]

Yeah! Between Green and Cyan is Spring Green and between Cyan and Blue is Azure, both of these colors are tertiary colors and are separate distinct colors that has many shades, tones and tints!

[@RogersJimmy-n4q]

@@user-od6ue9zv9u Well with yellow, you could have a goldish yellow and a lemon yellow. There isn't just one specific hue of yellow. Yes, yellow-green/lime green is different than plain old yellow, but yellow could have a tiny bit of green in it and still be considered yellow. Cyan can also have a little bit of green in it and still be considered cyan. It could also have a tab bit of blue in it and still be considered cyan. There is a difference between additive cyan and subtractive cyan. Subtractive cyan is a bit more blueish and one could say additive cyan could be a bit more greenish. Ideally additive cyan is pure cyan, with equal amounts of green and blue light. However, the cyan that the printer uses tends to be more blueish than additive cyan. All around cyan can be used to describe different colors other than one specific hue. Just like there is not one specific yellow.

[@RogersJimmy-n4q]

​@@user-od6ue9zv9u I would say that while a lot of those have blue in the name, they aren't actually blue or green. As my art teacher put it, there are an infant amount of colors it might seem. So people come up with bizarre names for them. She said the term fashion names. Chartreuse, cerulean-blue, maurve, those are all fashion names for colors. Since children are not taught about cyan in school, they just call it blue. While they might call it shades of blue or green, it's still cyan. You could take a red crayon and call it whatever you want. You could call it scarlet, candy apple, rudy, poppy, or whatever. It's still red no matter what you call it. You could call it pretty purple and it would still be red. Cyan and its different hues are still cyan regardless of what you call it. Companies like Crayola will do the same thing with fashion names. I had a robin's-egg-blue crayon from Crayola. It had way too much green to be considered blue even though it had blue in the name. True blue mixed with red makes a dark purple. Cyan mixed with red makes brown or some ugly color. Sometimes an ugly brownish green. If I took that robin's-egg-blue and mixed it with a red, it would still produce a muddy color because the robin's-egg-blue was still cyan even if Crayola named it blue. I did mix the crayon with red and it produced an ugly muddy brownish green color. There is still a wide range of cyan colors even if they have fashion names containing blue.

[@onetruetroy]

Terrific video! I’ve always liked to draw since I was 5, and used whatever art supplies were available whether crayon, pencils, markers, chalk, tempera, smudge… it didn’t matter to me. I learned more about consistency and palettes in high school, and never chose a color theory. If it worked and looked good then I was happy with it. I love gouache and chose a set that had the most vibrant and saturated colors, because they’re easy to tint, shade and shift. Even then, I select a palette that matches the most vibrant colors in the subject or reference. I prefer to have red, blue, yellow, green, orange, purple, cyan, magenta and white-I seldom use black. One of the important theories I learned was that light values are more important than matching hue. With today’s technology, I can easily look at the reference on my phone with the black and white, and greyscale filters. I’ll check my painting to make sure my values are as close as possible, even if the hues are off. By the way, mixing colors can easily be achieved by just painting them side by side.

[@tookitogo]

As a tech nerd, I read tons of technical stuff as a kid, and one of the things I read a lot about was printing (both press and computer), and that included _real_ color theory, not the phony-baloney RYB color taught in art class. Learning how color displays (TVs, computer monitors, etc) worked taught me about RGB color. I have said for _years_ that it does kids a disservice to teach them the patently wrong RYB color model, and I’m glad to see others say the same thing.

[@deborahgiles8214]

Oh! A topic close to my heart! I love having the knowledge of both CMY and RBY because it helps me mix a full range of colours from bright, clear and candy-like to muted and moody. I can't really express my consternation when I came from working with fabric to mixing watercolours and my knowledge of RBY colour theory DIDN'T WORK! I was horrified at the "purple" I was able to mix and wasn't happy with the green either. Now I like to have a warm and cool of each "primary" which covers all the RBY, CMY bases and is very versatile for mixing. That, along with mixing complements to get muted colours makes me happy. May I share a pet peeve? It's hearing the phrase, "don't mix X with Y; you will make mud." For one thing it's overused and trite and for another, we need a lot of muddy colours to paint our world, so it's a pretty limiting comment, in my grumpy opinion. Anyway. It's amazing to me how rapidly the theoretical framework gets super confusing and muddy. Just glad there are a few things to cling to that make sense!

FINALLY- as a lighting designer and filmmaker- an explanation for why RYB makes sense. This is really logical. Within my work- the RGB or secondary system makes sense for me... But I can finally understand why yellow would be a primary... not to mention within lighting design we often have an extra "amber" channel on our color mixing lights because red and green make a really ugly yellow!

[@saracosta620]

This just blew my mind! I don't remember being taught about colours in primary school, but in my Art classes in Portuguese middle school (year 5, we were 10 years old), we were specifically taught Magenta-Cyan-Yellow. Those were the primaries we used throughout the school system. I'm sure we were also taught about light, because I remember we had to make a paper windmill with the primary colours and then blow on it to see how the colours mixed and were perceived. That was in the 1980s, by the way. It is so heartbreaking to teach English colours and do the supposedly fun "Colour Maths" only to have the kids complain they can't mix the right colours. I usually tell them to use light blue and bright pink to avoid the disappointment (because magenta is NOT red), but now I've been reminded of the science behind it, maybe I'll ask the kids to make a paper windmill... and teach them magenta (which is the same word as in Portuguese) and sky blue for cyan.

It's funny, I've been meaning to do my own thread on Twitter about color mixing, and knew I'd run into additive and subtractive mixing fast, and the whole thing just gives me a headache. I don't know if you've run into Kids These Days (TM) calling cyan, magenta, and yellow the "modern" primaries, but they are. The explanation seems to be 'because that's what's in the printer' and I kind of hold my head and think "no..." but I don't open the can of worms. Add in I'm a history nerd who's studied the history of pigments. I feel that's a huge factor with all this; until the last hundred-odd years we haven't even had these colors to play with, to form the argument. Let alone the light-based media from televisions forward that begin the - additive? subtractive? I CAN NEVER REMEMBER - discussion. And did I mention, I paint? And love brights, so the CMYK palette is much more my speed, even though I know traditionally it wouldn't even exist. I would give a LOT of money to see what VanGogh would have done with modern paint. You did a great job on a bonkers topic. If you want to make your head swim further, look into tetrachromacy; we now have genetic documentation that yes, some women really do see more colors. Bonkers. The whole thing is utterly bonkers.

[@SarahRenaeClark]

The lightfast discussion is something I didn’t really know much about when I made this video, but it’s probably the biggest reason why modern painters haven’t fully moved to CMY. Magenta and cyan aren’t as lightfast as many of the traditional colors, so mixing every other color with them would be a bad idea for the longievity of the art!

[@jamesthaiss2899]

Hi Sarah, this is a great video. It's the only video I've come across that breaks down the color controversies so well. The more I research color the more I feel you are right that there is no one right answer. I've come to feel that CMY is the best color wheel to determine primaries. However when it comes to determining complementary colors CMY seems flawed since it shows yellow as the complement to blue which, when mixed together, as we know produces a green and not a neutral color. In this way I think RYB may be the superior wheel. What you said about the color being linear and not fitting into a perfect wheel I think is absolutely correct. I appreciate your work sorting through all the research and presenting in a simple, enjoyable way.

[@SarahRenaeClark]

It’s interesting you use this example, because there are a lot of online debates about whether blue + yellow = green. Because a “true” blue according to CMY would make black (or gray) when mixed with yellow… and you CAN replicate this with the right blue. But as we know, blue is used as such a broad term, and in MOST cases, produces a variant of a green. So using and teaching CMY again becomes limited and confusing in understanding how colors interact with each other if we dismiss the other theories completely. I don’t think RYB is superior, but I do think it is simpler in many applications. There’s another 4-color primary system that I’m exploring that offers a good practical option for artists that I might teach on in a future video.

[@jamesthaiss2899]

@@SarahRenaeClark Hey Sarah, I hope you are doing well. I'm back because after 3 months of looking online I still have not found anyone to show how blue and yellow paint don't make a greenish hue when mixed. It's not perfect green but it is clearly a green hue. If blue and yellow don't mix to make anything other than a neutral gray or black how can the CMY color wheel be correct since it has yellow and blue as complementary colors? I must admit I did not read the book that you sent me in the link above for 2 reasons: 1) it's a bit pricey on Amazon 2) it says it's a book about mixing colors and I'm actually more interested in the color wheel in terms of determining color harmonies. As a side note I actually completely agree with the idea of using split complements to mix more vibrant colors. It's been something I've done for years. But again I'm not looking for help with color mixing right now, I'm just trying to determine what is the best color wheel to use to determine color harmonies. It seems like while CMY may be decent wheel to use for mixing it's got flaws when it comes to color harmonies (i.e. blue is not the complement to yellow - how can it be? am I wrong?). The more I dig the more I think color theory is not as baked as some people say that it is. I believe you summed up this challenge well in your video when you described trying to boil down color, something that is linear, into a single color wheel, something that is circular. Perhaps something gets lost in that translation. Your video is one of the only ones that I've found that seems to hint at questioning the concept of color wheels. I appreciate that because it shows you've really thought about it and aren't just mimicking what 95% of the content online says. I've been trying to make color composition paintings for a couple decades now. The idea of composing with color is fascinating to me but in all honesty my success rate with these paintings is hit or miss at best. Composing with color is often a struggle for me. I've mostly been composing using my own gut instincts. Recently however I decided to really buckle down and school myself on color theory to at the very least make my color paintings a little less of a struggle. Who knows maybe it's just to learn the rules so I can intentionally break them and make something really exciting. I've been learning about color harmonies but I'm stuck on the color wheel. That seems like the foundation of all color theory. If the color wheel that I'm working from is not solid than none of it is solid, right? Ok, I've rambled far too long. Just wanted to share my thoughts. Color is an exciting subject. The journey continues. Have fun creating.

I use both. It depends on what my goals for appearance of painting will be as my general rule. If I’m going for a very high key painting I work with transparent colors in CYMK. If I’m working ala prima outside I use opaque or semi opaque RBY mostly because natural colors in daylight are going to be much less saturated and vibrant. Sometimes I use both system’s pigments in the same painting, though harmonizing them all is more complicated.

14:15 I still think that CMY should get taught to kids because if *cyan* and *magenta* were *taught* as specific colours, kids would easily be able to tell the difference between cyan and blue when they’re older. Even though I know cyan and magenta, when I see cyan I think of blue just as fast as I think of cyan, and that’s only because of the way I was initially taught about colour. That is why I think that we *should* discard the RYB colour model. If kids were *taught* CMY rather than RYB, they would have a much, much better understanding of the difference between cyan and blue. People only think kids won’t understand CMY because they find it hard to determine the difference between cyan and blue or pink and magenta. But that’s only because of what you were initially taught. If you were initially taught cyan and blue as different colours, you’d understand it just as well as you’d understand Ryb as a kid. Edit: And cyan’s difference to blue is the same difference as yellow is to green. The way you were originally taught will have a huge influence on your thinking when you’re older, even if you know what you were originally taught was wrong. Before the word ‘orange’ became a frequently used word in the English language, most people would have had trouble telling the difference between it and Red. I’m pretty sure that’s why people with ginger hair are often referred to as having red hair. A lot of young art students are giving up on their dreams because they can’t make a bright green or purple with RYB, their teachers tell them they aren’t doing it properly, when the real mistake is the colours that are being used. Being taught RYB is going to make it a lot more difficult to understand colour in colour science if you study that, and I don’t think there are any ways kids can *benefit* from being taught RYB. In my experience, it caused arguments, giving up on dreams and so much confusion, all of which are bad things. But are there any good things that come out of being taught RYB? I don’t think so. I can only think of neutral things and bad things. Another thing, cyan is not a cool blue-it is a different colour altogether. So many people think it is a shade of blue, when it is *vastly* different. Cyan is cooler than blue, but it is NOT a type of blue! Saying that cyan is a cool blue is like saying yellow is a warm green. It is not!

I don’t know the source of the definition for “primary” that you used, but that is not the scientific definition. If I wanted to select pink, orange, and green as my primaries, I could. The range of colors I could create with those (called the “color gamut”) will be quite different from RYB or RGB or CMY, but those CAN be my primaries in a color system if I want them to be.

[@mpetersen6]

Kodak and the other film companies figured this out long ago. But the Magenta and Cyan have to be based of a red and blue anyway. I do have problems getting bright colors when I need them. Personally I think it has to do with the wax coming out of solution in the color as it is played down due to localized heating from friction between the color and the paper. Paper is slightly abrasive. At least wood pulp paper is. Plus it depends on the species of tree used. Plus to get colors to really pop you need enough light. And the light needs to be in the right temperature range to give the hues a chance to come out. Fluorescents just do not work at all. This also applies to incandescents and LEDs. Our eyes are adapted to the specific light mix that we get from the color of the Sun's surface. Light that corresponds to other temperatures will effect how we see those colors. Hence the different temperature range builds manufactured and sold. As an aside people have suggested that if were on a planet orbiting around a red dwarf star that everything would have a reddish color. Not really. A red dwarf would still appear white or whitish due to the surface is still at a reasonably high temperature.
