firstly thanks for your videos, your enthusiasm for your subject shines through and is really inspiring! about how colour affects how light it looks, i remember my lecturer at uni saying it was based on how many cones it activates in the retina. we have three types of cone cells, activated differently by ranges of wavelength, peaking their response at long, medium and shorter wavelengths respectively. yellow light activates the largest number of cones so it looks lightest to us. orange and green, then red and turquoise, and finally dark blue and violet activate progressively fewer cones so they look progressively darker. if you're motivated enough, would you be able to do a similar video offering advice to traditional art. like tips on how to understand how this works when painting with watercolour, acrylic, etc.?

[@younesskafia4189]

What you're mentioning in your video is the result of different mathematical projection between color spaces. Imagining you have 3 spaces [RGB, HSV, Gray]. If you want to get an accurate point from one space to the other you need a function that will transit you to one space to another. Here you used 2 different function to transit from one space to another. One evens the 3 colors, the other applies a different function to the 3 colors to keep the same value. What you found is also part of the color toning techniques 3D renderer have to represent accurate/different dark values (Arri ALEXA for example)

It is and it isn't. Qualitatively, a lot is known. But quantitatively, today's standards still often assume a color space that fits on a regular screen. Very high saturations combined with very high dynamic ranges are still not that well-fleshed out it seems. Lots of approaches exist, but none of them are entirely perceptively uniform across the entirety of our vision. Progress is being made though. And for the LDR/sRGB domain that this video focuses, things are working pretty well by now.

Keep in mind, all of this was done in sRGB space. While it's useful for storing colors, it isn't so great for picking or modifying them. Using a perceptual space, such as Okhsl (which has been added to Photoshop since this video was made), will alleviate some of these issues. Also, the triangle-type pickers work somewhat better because they are an approximation of a perceptual color space. If you take a slice of hue in a perceptual space, you will get a roughly triangle-shaped "flag" of color, with grayscale on one side, and the most saturated point at the tip. However, the shape you get will not be a perfect triangle, and its shape changes depending on hue.

[@user4241]

As a color nerd, yes, you are completely right.

[@HM-xw7gp]

I'm very interested by this, I'm having a hard time understanding how colors and values work, I don't really understand how the different spaces available work and why they're different, but I'm so eager to learn One thing I didn't get from your comment was in the first part, what did you mean by "while it's useful for storing colors"? And also you said the shape of a slice of a perceptual space will vary based on hue, do you know of any website where I could see what this shape should look like for different hues? Does it rely on the greyscale of each hue?

[@dalmationblack]

A function I learned in a CS class that might be helpful to understand this phenomenon is how to calculate luma. When converting RGB to grayscale, there are a couple ways you can do it. A naive way is to just average the R, G, and B values, but this has the same problem as removing saturation did in this video. A way that's more accurate to our eyes is to calculate the "luma" of each pixel, where luma = 0.2126*R + 0.7152*G + 0.0722*B. (The reason this is more accurate is probably something to do with our eyes being more sensitive to green light than to red and to blue). This is almost certainly what photoshop is doing under the hood when you change colors to grayscale. It also reveals why the blues end up so dark, because there's a very low coefficient on the blue values of the pixels compared to red and green. Yellow, having both red and green, ends up the brightest after the luma conversion.

[@beeble2003]

The luma calculation must be about more than just eye sensitivity. The human eye is not very sensitive to blue, which is reflected in the low coefficient for blue, but it's about equally sensitive to red and green, whereas the luma formula is very heavily biased towards green.

[@SplendidKunoichi]

@@beeble2003 it's because the eye isn't actually sensitive to red or green. what you might instead say is that it's (very) sensitive to the absence of blue it follows that the resulting spectral distribution must be dominated by green light, since whatever range of frequencies you consider to be red is limited by and around the lower extreme of the visible spectrum itself; meanwhile whatever wavelengths you call green get to range more or less as far as you want in both directions from somewhere around the middle of the visible spectrum

[@beeble2003]

@@SplendidKunoichi That doesn't make sense. Darkness and green like are both "the absence of blue" but both look very difficult. And "whatever wavelenghts I call green" are limited to being between red and blue, whereas red can trail off as far into the infra red as you want to call "visible".

[@SplendidKunoichi]

​@@beeble2003 the key here is that "visible" is not subjective, even if the color names are. "the absence of blue" is a fancy way of saying "yellow", but really it could mean any number of different colors, so long as you can find them on the rainbow; that is, it has to be visible. red light indeed does always "trail off" into invisibility no matter how you slice it. infrared light is invisible; infrared is not a color. wavelengths composing greenish light never do this because spectral green is bounded on either side by other colors (red and blue as you say) that are just as visible albeit not as bright, again no matter how you slice it. it's hard to describe without getting into the math, but visible or not there's a finite amount of light/radiant energy present in the spectral distribution, it just happens that this distribution peaks in the very middle of the frequency range detectable to our cone cells (ie. the G in ROY G BIV). outside of that, spectral red and violet are only seen as very dim side-effects of metal glowing red-hot and cheap blacklights that leak into purple. we can perceive the corresponding IR as warmth and UV as sunburn, but never as color.

[@beeble2003]

@@SplendidKunoichi OK, that makes sense. Describing it as "not-blue" was just a completely unhelpful way of saying "yellow", which is a completely different thing.

[@Sarah-pt2zj]

I'm a traditional artist, I think something like this is more intuitive when mixing paint. Gray is made with black and white, and white will always lighten. So it makes sense that a mid gray (meaning a lot of white was added) will be lighter than a pure blue pigment out of the tube. Similarly, it's common to lighten a color with yellow and no white, making it obvious that yellow is lighter than the other colors. I think it's beneficial for people to at least play around with mixing colors even if they're a digital artist.

[@79sketches]

[@79sketches]

@@AlejandraRafa thank you!

[@PauloSousa86]

The thing is that color saturate or has higher chroma at different brightness levels, so a saturated green or yellow will have a brighter color value, red usually saturated at 50 per cent and blue saturates darker. That's why you can't get a dark saturated yellow for example, also in photography they use colored filter in enlargement machines to control contrast on developing film to paper and that why it is used red as color for the light on those rooms

[@StrawberryLegacy]

Well, technically that's only true for opaque mediums. In mediums like watercolor you can have a yellow that's so transparent it has almost no effect on value, only on hue (for example Nickel Azo Yellow PY150) For digitital artists: transparent paints are basically always set to multiply. That's why your point with mixing grays is a good one though. With transparent mediums/color multiplication you can mix two colors of very high saturation AND value, like magenta and green, and get a perfect black with extremely low value. It's really fascinating when you think about it - but it makes sense when you remember paint mixing is subtractive. If a color is completely saturated, it means the rest of the spectrum is absorbed completely. Which results in the whole spectrum being absorbed when you mix two highly saturated complementary colors together and you get black. Gosh, I love color theory.

[@yay29823]

Isn't green a cold color and magenta a warm color? Green is lighter then magenta

[@Kaori246]

The brightest colors will be the ones between red and green, closer to green, which is where yellow sits. It’s the brightest because it contains both red and green. Blue is the darkest, so the darkest colors sit between blue and red, but purple is brighter than blue because it contains red, which is more luminous than blue. In short: Brightest - between Red and Green Mid - between Green and Blue Darkest - between Blue and Red Desaturating adds more colors, so it equals in brighter colors.

[@karlhendrikse]

What you're seeing is just what the conversion to grayscale is doing - it's setting the value of each pixel to the luminance (not the value) of the original color. Luminance is a perceptual quantity that is the same for two colors that appear to have the same brightness. Value is a mathematical quantity that's just max(R, G, B); it doesn't mean much in terms of human perception when compared between different hues and/or saturations.

[@phlimy]

^This should be top comment you seem to be the only one here who explains the situation accurately

[@dannydewario1550]

@YumeLeaf CyanideWater I0 But cameras don't work the same way our eyes do. Just because our eyes perceive colors a certain way doesn't explain why blue has a lower value than other colors. Now I think the original comment's explanation makes a lot more sense because it relates directly to pixels. I'm willing to bet that if we could only see in black and white, blue light would still look darker than yellow light. So this phenomenon has nothing to do with our perception of color.

[@phlimy]

@YumeLeaf CyanideWater I0 Answering your first comment: That's exactly the point. Photoshop does NOT just take the value and throw away the rest when you switch to black and white. It instead uses a smart formula based on our perception of colors to create the grayscale pixels. So when he says "different colors have different values", it's not exactly right. Value doesn't care, it's an axis orthogonal to the hue. What he actually means is: "Photoshop will convert different hues in grayscale in different ways to more accurately represent our perception."

[@Thytos]

This comment needs more upvotes. While watching the video I also thought: There's not _the_ greyscale conversion. There are different ways of converting color to greyscale and the conversion he's doing in Photoshop is apparently not just picking the brightness value.

[@megamef]

@@dannydewario1550 Actually they sort of do. The cones (colour sensing parts of eyes) are about 60% green, 29% red and 11% blue).

[@EchoGillette]

It's because of the cones in your eyes! =D I NEED to make a video about this, but essentially the 3 color receptors (red, green, blue) in your eyes aren't equally sensitive. Green cones are the most sensitive and blue cones are the least sensitive, so when your 2 most sensitive types of cones are both stimulated (green + red) you see yellow! =D The only color more stimulating to your eyes is white, which is ALL cones. That's also why blue is the darkest pure hue. Because its the least your eyes can be stimulated apart from NO stimulation, which is black/darkness.

Perhaps you're missing more information about colour spaces. Colours can be perfectly represented in 3D space, but each axis will not necessarily mean something intuitive. That is why we have many 3D colour spaces. If you want one space where one axis represents a realistically perceived bright/dark measure, use HSL or LAB where L is luminance which is meant to be perceptually accurate. HSV, on the other hand, has V for value and it only makes sense mathematically as it is a convenient way to have a saturation axis S that represents deviation from pure grey linearly.

[@DeliciousOrange]

I'm going to wager the perceived "darker" values of red and blue hues has more to do with the sensitivity of our eyes to those color frequencies rather than their physical wavelengths directly. Since seeing "yellow" requires two of our three different receptors to be firing that excess of signal travelling along our nerves probably overloads our sense of 'value' and makes that hue appear "lighter" other hues. You'll see the same effect happen with cyan, which requires our blue and green receptors to both be sending signals at the same time as well.

[@jeffsfolio]

Great observation. This is quite accurate.

[@Mikapoofs]

since our eyes are more sensitive to red and green vs blue, it'd also make sense that yellow would be the brightest, as opposed to magenta and cyan that require mixing less sensitive blue receptors

[@asdfniofanuiafabuiohui3977]

our cone sensitivities overlap with each other, the green cone overlaps with both red and blue more than red does with blue and vice versa, and the brain reads the intensity of each of the cells combined. So green would be the most intense, however yellow is right at the overlap of green and red, making it the largest value out of all. (also blue our sensitivity is lower than other cones)

[@HenrikMyrhaug]

That's not really right. The names we give colors are determined by how often we see the color. When we see yellows, we almost always see bright, highly saturated yellows, while rarely seeing dark or less saturated yellows, so we only named the shade of yellow that is bright and highly saturated. Red and pink are named as different colors, since whenever we see bright reds, they tend to be very bright (skin, flowers etc. are usually very bright reds), and whenever we see darker reds, they tend to be much darker(blood, flowers, fruits, all usually have a dark red color). We often needed to distinguish dark and bright reds, so they were given different names. Meanwhile, we keep seeing all different brightnesses of blue and green, and we didn't have any use for giving the different brightnesses different names, so the names were used as blanket terms for all brightnesses. We have always been able to tell apart different colors and how bright they are. It was how often we saw different colors, and how much we needed to distinguish different shades that dictated what colors we decided to give names to. Those names stuck, and now the names are used for colors of wildly different brightnesses.

​@@adrianks47 The formula you have shouldn't be named greyscale, it's miss leading. True greyscale is the average of RGB. Y = (R+G+B)/3. If it takes into consideration the human eye perceived color they should name it average human perceived greyscale.

Something that's happened to me is that blending modes like "Hue" or "color" don't let you paint with for example, a really dark yellow, or a really Bright red without it looking like something else. Hues have a "Range of values" in which they are readable. Color theory is hard

Not really. Just look at what you have use to describe those colors, sun „shine“ yellow and „deep“ purple. You have unintentionally already put in value into your colors. The „shine“ color should be lighter than „deep“ color follows our intuition. However, what this video pointing out is that, even a color A with a higher value(brightness) is seemingly darker than a color B with lower value(brightness). That doesn’t follow our intuition and I would say very confusing.

[@supplespecimen725]

@@brpk9377 but if colour A is purple and colour B is yellow, we instinctively know, and can visually tell, that this “bright” purple is nowhere near as bright as the “dark” yellow. Purple is just a darker colour. It’s like if there was a very wide spectrum of light-to-dark that all the colours fit into, no colour would be able to take up the whole spectrum, leaving us with yellow on the brighter end and purple on the darker end. Blue would overlap somewhat with purple, but wouldn’t be able to be quite as dark, and yellow would only be able to be darker than the very lightest purples. That’s what we mean by “purple is inherently darker than yellow”, the darkest yellow is never as dark as the darkest purple because they are on two very opposite ends of this spectrum. Maybe its just a difference in how we grew up visualizing colour, but it really doesn’t seem that confusing, I’ve known this since early elementary at the latest. As for “deep” purple and sun”shine” yellow, that’s just a description of what the colour looks like, no? Sunshine yellow looks like the glow of the sun on a hot day, deep purple looks like it could stretch into an abyss. This is very abstract, i know, but how else are you supposed to describe a colour?

[@lemonadegrenade8523]

Your tutorials are literally the best ever

[@svenhegenmusic]

Ok here's a bit of explanation on a few things you seem to be confused of. The color picker: Your color picker is set to HSB/HSV (same thing), not to HSL (technically there is a difference between HSV and HSL - the L stands for luminance). If you pick two colors with different Value they should in theory stay different in Value when you desaturate them, and that's exactly what happens when you use the HSL-saturation slider shown at 4:50. The HSL-saturation slider does exactly that. It decreases the saturation while keeping the hue and value staying the same. Interestingly enough photoshop now calls it HSL (Lightness), but it's actually HSV as seen in Coral Painter. Oh it gets worse.. in Clip Studio Paint they call it luminocity (but with a V in brackets.. wth). Anyway. Let's say you're using a different way to desaturate the image. How does the desaturation work? One way would be to extract only one channel from the RGB channels and apply it to all the other channels. Cheap digital cameras use this method when applying a build in black and white filter. They overwrite the red and blue channel with the green channel, to get a greyscale image. But that's actually a bad idea. Why? because areas with strong colors like magenta that doesnt have any green in it at all will come out as black or really dark. Moving on what else could you do? You could convert the colors to HSL (luminance) where bright colors like yellow and cyan actually stay bright and visually darker colors like blue and violett stay darker and then strip away the saturation. That way you would at least get an accurate representation of the brightness of the colors in the greyscale image. Actually a good way would be to convert to LAB - wich stands for Luminance, A and B (but wth is A and B???? they are color channels. look it up, it's quite interesting) and decrease the contrast in the A and B channel, that way you only keep the luminance channel. But... you need to convert between RGB and LAB and stuff and that sucks and yeah.... Where am I getting with this? Color theory, especially digital, especially color science, especially with all the f*ing weird lingo is weird and it's complcated and the more you dive into it the more confused and frustrated you get... Let's maybe just... accept that it is what it is and move on before we loose all fun at doing what we're doing? Because I mean that's why you do it right?

[@FlameRat_YehLon]

HSB and HSV names the same thing, but keep in mind that not all software use the same color plotting. Picking the HSB/HSV value from one software and input that directly to another software might not yield the same color, even if both are properly color managed and set to the same color space. Same for HSL I think, but since it's more niche I think it's a bit more unified across software. Also, it's not uncommon to adjust the greyscale conversion matrix to need. For accurate soft proofing result though, we have a few "standarized ones". But unfortunately there are multiple of those. Lab is a good one though as in math that would always be accurate, except... It has to be converted to RGB at some point eventually. And the conversion matrix is also subject to standard variance. And... We still can't see accurate color. That really sucks when think of it, but again Lab is more of a garage dragon to begin with anyway. And... When all of above is solved, we now have HDR and wide color gamut image to deal with. And things just goes so wild that I personally just gave up and decided to go SDR and sRGB for life. Anything else I can probably have by buying a bottle of pigments I guess.

i just see it as the “darker” colors absorb more light, the “brighter” colors reflect more light, so the darker colors will have a darker hue. kinda like color changing light bulbs. you can have the brightness set to 100%, but the white light will light up more of the room than the yellow light, yellow will light more than the green, green more than the blue, blue more than red, etc.

[@Keijo_]

But what makes any of those colors "brighter" or "darker" than one another, especially when there is a brightness and darkness adjuster already built into the color pickers? That's the question the video is asking. Why are some colors brighter at the same values, and what physical properties does that relate to? My best guess is that it has to do with how the colors are created digitally using rgb, because those three colors appear generally darker while colors like yellow magenta and cyan which are made by combining colors are mostly brighter after grayscale is applied, presumably relating to how many subpixels are activated to create each color. For example the brightest yellow would be (255, 255, 0) while the brightest red would be (255, 0, 0), half as many subpixels being used. And in terms of pigment the effect would work similarly but in the opposite way, where cmy are the primary colors and are combined to make other colors. Since this form of color is subtractive, rgb would still be darkest as more light(specifically a greater amount of different wavelengths)would have to be removed to create those colors. Although the details are less obvious to me than with digital color because I don't know how the hues are created

[@oldtobie1]

@@Keijo_ You are on the right track. Our psychological response to a color is based on how much the color activates each of our three color "cones". Humans are naturally much more sensitive to green/lime/yellow than red or blue. We can distinguish hues more accurately there and we see them as brighter even if they are the same intensity. When a software application "greyscales" a picture, it uses a model of the human color response to determine the average cone activation, or the "luminance" of a color. A pure blue pixel (0, 0, 255) has maybe half the luminance of a pure green pixel (0, 255, 0). Blue lightbulbs don't illuminate a room as well as other colors for the same reason. Blue light can bounce around the room, but our eyes don't pick up on it well. It has nothing to do with whether they "absorb more light". They're not absorbing light, they're producing it.

[@jorriffhdhtrsegg]

It would be the firing of two simultaneous cones perhaps and our eyes bias toward green (camera sensors tend to have many more green sensors). Another is "yellow" is defined by its lightness. Try making 'dark yellow'.! You end up with greenish brownish mud it doesn't exist any more than 'dark pink' due to pink (not magenta!) Being a 'light red'. Its just an issue with colour space probably. To make pink i.e a lighter shade you add white which in turn desaturates. On the terms 'value' does not figure this and only represents the max firing of a hue, whereas in other models its termed 'lightness' which by definition factors these 'tints' (add white) in and is coupled with 'chroma' not saturation. Chroma differs by being invariable for lightness... Yellow is not the same as 'light cyan' of equal chroma in lightness in such a colour model.

Its going to depend on whether we are talking about additive or subtractive colour. Be careful not to conflate the two.

this can be fixed almost entirely by switching to the LCH colour space. It's essentially the same, but hue and saturation are properly decoupled from value. This is because it's mapped to human perception of colours, not the RGB gamut. I don't know if you can do that in Photoshop, but I tend to design on the web using chroma-js which supports this colourspace. AFAIK the reason this happens is due to the cones in your eyes having different sensitivities to wavelengths of light.

@@memyself4852 the CSS color models aren't great. You really need to be using a professional color managed program. Photoshop should be (used to be) the gold standard for color management (if you could navigate the settings) The big issue is that you cannot maintain max lightness and max saturation at the same time, and the amount of loss varies by hue. That is why the LAB and other models where saturation is derived work better for maintaining lightness.

[@giffardjustin]

So I oddly learnt about this in one of my computer science modules (possibly computer vision). Its got to do with the way we perceive colours. We have 3 receptors to see, red green and blue. Green is the most sensitive, red sort of in the middle and blue the least sensitive. The way we convert from RGB to greyscale is based on the way we see the different colours and if you looks up the formula used to convert to greyscale its Gray = 0.299R + 0.587G + 0.114B. Im just looking at the formula for converting RGB to HSV and it doesn't really make sense to me... Id have guessed that it would be the same as the conversion but turns out that would be the lightness value and there are different conversion standards... the above is SDTV standard (aka recommendation 601). Adobe used Rec. 240 and it is Y = 0.212R + 0.701G + 0.086B. HDTV used Rec. 709 which is Y = 0.2126R + 0.7152G + 0.0722B. UHD and HDR used Rec.2020 which is Y = 0.2627R + 0.678G + 0.0593B. Interesting! To get the value of HSV it its the intensity of the colour thats has the highest intensity so which is bizarre to me because that implies that if as long as you only change the values of colour channels that aren't the highest intensity the value won't change? (255, 0, 0) will have the same value as (255, 200, 200)? Back to to the brightness if you have pure blue (0, 0, 255) and pure green at 20% (0,51,0) they would have the same lightness which according to my quick test pinta (I don't have photoshop) yes they do as they grayscale for both are (29,29,29). For what its worth to get red to the same value would be red at 38% so (97,0,0) All very interesting stuff and my mind is officially blown. I wonder if there are any paintings where there are secret messages hidden that can be revealed merely by putting it into greyscale. I know that there is a way of adding secret message to images by altering the RGB value by 1 and then when the intended receiver uses a program to compare the original to the one they were sent they can get the binary from it and decode the message, pretty genius actually. Called steganography and technically hiding a message within a picture that can be seen by making grey scale would also be a form of steganography

[@billyswong]

Rec.709 and Rec.2020 are using a different standard of "red", "green" and "blue". Rec.709 primaries documented the capacity of CRT monitors in 1990s. Mainstream computer photos and videos also use this same set of RGB primaries. Meanwhile, Rec.2020 specified a set of purer "red", "green" and "blue" than what we had in the past, using a single wavelength light. (piano vs. tuning fork) The recent iPhones are taking photos and videos in P3 color space. They used the same "blue" of mainstream but a purer "red" and "green", albeit not as pure as Rec.2020. Another factor is gamma. sRGB, what mainstream computer photos standardized on, is slightly different from Rec.709 here. But that doesn't matter. What's matter is that "20% brightness" doesn't mean a 255*20% RGB value. You need to put the 20% brightness into the gamma curve. A (128, 128, 128) pixel is emitting significantly less than 50% light of a (255, 255, 255) pixel. (We feel 50% because human perception is not linear.) Uncalibrated LCD monitors and TVs may or may not fit the curve exactly as specified but they still roughly follow suit. GIMP converts (0, 0, 255) into (70, 70, 70) for grayscale. Your (29, 29, 29) looks strange.

In RGB, on digital screens, it is vital to understand that there's a huge difference between the objective brightness between RGB and CMY the reason is simple: for red we have one light active, just the R in RGB, yet for yellow we also add green G, so digital yellow, magenta and cyan are about twice as bright as red, green and blue respecticely. add to that the specifics of how human cones perceive color and it becomes a bit messy, but that inherent distinction between the hues on digital screens is important

@Kyaru Momochi Depends which hue you are talking about. If you are talking about computer hue, then there are accurate color pickers. Accurate doesn't mean corresponding exactly to reality or peception.

@Kyaru Momochi Something is not flawed just because it doesn't contain every single color a human eye can see. Sometimes I don't need to know what a picture looks like printed out, but only what it looks like on a computer screen, and in those cases color pickers are not flawed, they show exactly what you what, what it will look like on a screen. Sometimes I just need to see all the colors the computer can produce, not all the colors I can see. A color picker that does that is not flawed, its doing exactly what I want.

Wow I caused a scientific debate

[@sanri313]

thank you man this helped me greatly as I was always frustrated by my color choice...this explained a lot

[@sammymilkshake2210]

Thank you for explaining it. You are the first who has made it make sense. At least enough for me. This is a start. I may not be able to apply this knowledge yet, but that's for the push!

[@InternalStryke]

I remember reading about how each hue has its own inherent value, yellow being the brightest and purple being the darkest. Johannes Itten actually made a brightness scale of each primary and secondary color

[@karakurie]

One of those things fine arts teachers can never teach us. I never knew this...I assumed it because for some reason all my pics turn out super dark and I can't control my lighting. Makes sense! Thank you!

[@RagnaFenrir]

To sum it up, this is a good explanation of how bright/warm and dark/cold colors work in greyscale

[@m1lfmanilovefishing823]

Thank you for this explanation. i was told not to just turn down saturation before but when i asked why, they couldnt explain. this makes the reasoning easy to explain and follow.

[@AnimationGym]

Wow and i was thinking it’s just in rgb images When converting rgb image to greyscale , the color channels contribution will be like this 30% red 59% green and 11% blue and averaging the the value by 3 Thanks for the art and science lesson 🙏

There you go -> 🥇🏆

[@randyruedisueli7470]

This is a great explanation! Value / color is my biggest struggle, especially value. Awesome video thanks!

[@thesharkq]

you literally just blew my mind . i’m pretty sure i’m never going to colour anything ever again

[@spaderkungskuk]

The different algorithms for convert to grayscale by either “convert to bw” or “decrease saturation” is not explained, yet everything centers on it. Also I miss the obvious gamma discussion when comparing how we perceive the linear color space when it’s modified.

[@boitahaki]

I recommend reading "The Dimensions of Color" by David Briggs

[@bobbysands5385]

Great stuff, Marco! Thank you!

[@spongebobssponge1224]

This is absolutely mind-blowing
