[@vincentwilliamcarmichael4257]

Thank you, thank you, thank you, Ethan! I'm learning to paint again after more than 30 years and though it's all so exciting, so fun, and so new - it's also been somewhat intimidating. Not only is painting fun, expressive, & creative, it can also be relaxing and meditative. But... then there's me fighting my "perfectionist" self. The one who always says, "This isn't good enough, you can't really do this, and you should just give up." Well, I'm not giving up this time and after a couple days searching on KZbin for a good "color theory" explanation and the subtractive vs additive thing, I've found THE VERY BEST EXPLANTION on KZbin; YOURS! So again, thank you for sharing this information more than 4 years ago! I feel like it was made especially for me... Anyways, I'm going to go and paint a color wheel now... :) This is great!

[@Kenvie2000]

This was a good video. I was a little overwhelmed when it jumped from the mixing of the CMYK to the RGB and how you view colors with the shirt, so I'll just have to watch it again. But thanks for all the info.

[@alanp741]

This explains ALOT. Since I paint digitally, I guess I'll need to use the RGB but if I'm painting with ACTUAL paints I'll use CMYK

[@EthanAvery]

First off, wow, idk why this video suddenly has tons of views, thanks for watching! Secondly, you're mostly right but, you can actually use both RGB and CMYK in most digital painting programs. For instance, in Photoshop, using the blending modes (Normal, Lighten, Darken, etc...) allows you this option. Using Lighten will replicate RGB (Additive), Darken will replicate CMYK (Subtractive).

Perfect explanation of basics

[@eugenius3302]

Interesting video. I tend to favor the RYB model myself. Did you know that in the RYB paint pallette Phthalo Blue is often cited as the primary blue? It is made from a chemical compound, Copper Phthalocyanine. It is a blue pigment with a cyan undertone, hence it is called blue when in its opaque form. The cyan used in inkjet printers uses an aqueous solution consisting of Phthalocyanine. The "cyan" in the additive spectrum is actually more of a Turquoise color than Cyan.

[@georgebrankov2143]

I also. Yellow seems more as a primary color than green. And the blue in rgb looks like an indigo color. It's more purple.

Hello Ethan, thank you for your video. Why are the primary CMYK colours not simply red, green, and blue too? They mix the same way as RGB colours do.

[@shatouri5920]

[@avramovskae]

In CMYK the letter "K" is for KARBON which comes from the Greek word for the chemical element carbon

[@ColonelSandersLite]

It's actually 'Key'. It's a term of art in the printing industry and has been for ages.

[@GodittoC]

How do I make the colour indigo(a darkish blue) in RGB?

[@EthanAvery]

Sorry I'm super late to answer this as I've been off youtube for a while. But you can make a dark blue by adding a little black into your blue (assuming we're talking paint here). Adding some Red will make it a little more purple and orange can help to make it a little more neutral. Sorry again for the late response!

Hi ! I hope u can notice me im from the philippines, sir. I have a printer L130 sublimation ink. My printouts were fine. But when i used heat press on my drifit shirt using sublimation paper, the gray turned into green shade. From what i saw here, yellow and cyan is equals to green. Does that mean i have to lower my yellow and cyan before i print my image design??? Plss help me.

[@EthanAvery]

Hmm, I'm not a printing expert specifically, but if colors are coming out correctly, then it might be either the shirt or the type of heat transfer paper that's causing the issue. If its not too much trouble you might want to try using a different type of paper and/or shirt, as well as checking your heat press to make sure its running correctly.

[@obaidurrehman707]

This video was so good but only one thing that I don't understand is White -blue=yellow????? Please tell me about this.

[@EthanAvery]

Basically, the way it works is red and green make yellow. Looking back on the video now years later, me using white to explain it can make it quite confusing. But the important thing to know is that red and green together make yellow, hope that helps!

[@archive2500]

If you see white light, it means there is an equal mixture of red, green, and blue light, so if you remove the blue light from white then you will be left with red and green lights, in which, when mixed, they produce yellow light. Mixing red and green in pigments such as in paint, will produce dark olive or dark drab (which is almost black), which is basically very dark yellow. Interesting?

[@PhilipposPappas]

"cyan'' derives from the Greek adjective "κυανοῦς" which means dark blue, so it seems there's some confusion in English use...

[@rashijain8037]

Thanks but why we use RGB for screen and CMYK for print.

[@jamessmith65536]

We use RGB not only for screens, but any light-producing device in general. This is because of our cones in our eyes, they detect red, green, and blue colors. That's why these colors are the primary colors for lights. Now, the mechanism for light is inverted in pigment. Instead of being lighter and lighter as hues mix, mixing hues in pigments causes the mixture to turn darker and darker. Just as like when you mix more and more colors in paint, watercolor, crayon, etc. And if you actually invert the red, green, and blue, they will turn into cyan, magenta, and yellow. You can test that on your phone, take a photo of things with accurate colors red, green, and blue the same with my profile, and you would see they result in colors cyan, magenta, and yellow. So just remember these two key things: We have two principles of color: * Additive mixture - It will make the mixture lighter and lighter as three hues mix. It uses the RGB color model. * Subtractive mixture - It will make the mixture darker and darker as three hues mix. It uses the CMY color model. And if you see white light, that is the resulting color when you mix red, green, and blue lights. In pigment instead, cyan, magenta, and yellow pigments will produce black when mixed. So next time you buy paints, make sure you buy cyan, magenta, and yellow.

[@dantan357]

Can you make a video show what happens if you have a colored light like yellow or blue what would the shirt reflect?

[@EthanAvery]

Sure, I think it could actually make for an interesting video. Also, sorry for the late reply, I've been off KZbin for awhile.

[@allsber]

If you have a colored light without any white in it, it would reflect everything on a grayscale. Th

[@kaliprasadkandula20]

Oh man your explanation blew me off

[@christophergrove4876]

I am a large-format printing technician and graphic designer. Here's the problem with your Subtractive model while referencing an inkjet printer. Basically... it's wrong. What you stated in your video would be mostly true if you were mixing paint. (I say mostly true, because as an oil painting artist my father showed that the quality of oil paint pigments gave varying quality results, sometimes resulting in muddy colour where you wouldn't expect anything but a pure colour.) If you look at an inkjet printed colour image under a magnifying glass, you'll see that the inks aren't actually MIXED at all... they are dots of each of the CMY(K) colours SIDE-BY-SIDE - "Process" colour. If you were to actually mix any of those inks together - depending on the specific pigments used - you get variations of muddiness. ALSO, if you are looking at the printed sheet under different TYPES of white light... fluorescent vs the sun vs a light that is made up of separate Red, Green and Blue LEDs You'll see various colour shifts. What we were taught in elementary school is NOT QUITE the story.

So when we think an object is a certain color, it actually is the exact opposite color we see it as? Is life all a lie?

[@snuffles7492]

lmao

[@archive2500]

If that is how you interpret it then yes. Lmao! Haha. But it just means the opposite color is being absorbed and the reflected color is what you see. White objects absorb all colors, in which, black is "absorbed" (because mixing all colors will produce black) and then white is reflected straight into your gazing eyes.

[@ItsJayYork]

you said you were gonna explain the "pigment and light" colors but you never really did, how come printers use CMYK but artistic pigments still work with RYB?

[@jamessmith65536]

Because the RYB color model predates modern science. Printers are electronics and scientific advancements that are made pretty recently compared to when the RYB color model was made, that's why they are more advance and therefore, more accurate in the same way electronics use the RGB color model for lights. I don't know about these adamant painters that still use dull and dark-hued RYB colors these days. Pigments are pigments, there are no exceptions, there are no artistic pigments, there are no pigments that violate the principle. The subtractive color mixture principle is consistent, it applies to any pigment, that's why the CMY color model works better. It has a larger scope of colors, the same scope with RGB, which basically the color model almost all gadgets use currently. The way how color behaves in lights is opposite in pigments. So basically, the opposite of the primary colors of light, red, green, and blue, will be the primary colors of pigments, which are the cyan, magenta, and yellow. You can even test on your phone, take a photo of things with accurate colors red, green, and blue the same with my profile, and you would see they result in colors cyan, magenta, and yellow. I don't even understand how some people still ignore the fact that it's logical that these two color models (RGB and CMY) are opposites. The RYB color model is just established in almost any place, but that doesn't mean they're better. If you invert colors red, yellow, and blue, they will result in colors cyan, blue, and yellow, I don't see any gadget uses that color model for their lights. Do you know any?

[@EthanAvery]

Well said Jasper. Also I don't know any technology off the top of my head that uses RYB as its color model for lighting.

@@user-od6ue9zv9u The indigo color is actually Blue-Purple. Cyan is Blue-Green and the real blue is in between them. Cyan is a tertiary color according to RYB and subtractive according to RGB. Cyan plays almost no role in culture, technology and compiters so it is not as popular as the colors orange, amber and vermillion for example. I doubt very much, Newton was color blind and couldn't tell the primary colors from the mixed ones like the cyan & indigo.

So does basic colour theory still apply? Do i have to forget the basic theory? Also so the basic colour wheel primaries are essentially still in the CMY wheel only as secondaries, and that makes what was secondary in the basic wheel tertiary colours in the CMY wheel?

[@EthanAvery]

It's probably best not to think of CMY and RGB as color wheels, but instead as models (basically the models (additive, subtractive) determine the way colors mix together, depending on whether you're dealing with light or pigment). The color wheel however is more so to help you get a general sense of color relativity (Warm/Cold colors, Complimentary colors, etc...). So 'basic color theory' does still apply (Complimentary colors are still complimentary, regardless of which model (additive or subtractive) you're using, however the model you use decides how the colors mix. _____ The CMY model secondaries are RGB, but RGB are not the primaries for the 'basic color wheel'. People tend to use RBY for that. Also, the secondaries in the 'basic color wheel' Green, Orange, Purple are not tertiary colors in CMY as you can see because Green is a secondary color in the CMY model. I know it can be quite confusing, but thanks for watching, I hope this answers your questions, let me know if you have anymore! : )
