      @@user4241 Be careful when you say "spectrum", because it may mean the part of electromagnetic field oscillations (photons) which human eye can detect or the gamut of colors which people sense. Both overlap but not in a simple way; for example: people sense colors which they cannot find in the physical spectrum.
      Sensed color is a psycho-physiological phenomenon, a result of physical stimuli but only after many stages of processing.
      There is some evidence that that it may be even social.
      Quite often people cannot agree of what color some thing actually is ...(remember the Great "Blue" Dress Debate?)

      Kuvina explained this in the video so it’s likely user4241 made it 5:20 into this 42:34 length masterclass, threw their hands up, and bounced.
      The “spectrum” is the slice of visible wavelengths along the electromagnetic spectrum (wavelengths are monochromatic by definition). Kuvina explained this is the reason we utilize normalized responsivity to construct the “visible gamut” from perceived color. The vast majority of colors we perceive in everyday life are not single wavelengths so this derived gamut allows us to populate the rest of that color space in a mathematically sound way. Bonus that it maps onto our “Newton’s prism spectrum” in a way Newton would likely nut over.
      TLDR: Kuvina explained that the band of color dispersed from a prism are not monochromatic (unlike a mathematically exact nm spectral chart) and this dispersion and subsequent retinal perception creates that cyan (and many others) user4241 said Kuvina left out.

      @@FuriousTortoise You correct.
      In fact 40 or so minutes is way not enough to cover the subject of color perception and production. My 1st experience with it was reading a (East?) German (translated to Polish) book on the subject a long time ago, but with beautiful illustrations, it was "only" 400 pages long and it did not cover yet the computer vision or the newer neuroscience. But it went deep in the reproduction of the color in print and photography.

    There is one important thing, that is easy to miss: the values 0..255 in "RGB" are *not* true RGB values - they are square roots of RGB values! That means, that the "middle" value of 128 is not 50%, but only 25% brightness. If you mix colors in that non-linear "RGB", you'll get darker colors, than they should be!
    The reason for that is CRT monitors, that had quadratic response to input voltage. To save money on consumer side, they decided to put correction on the production side. Also, human perception is more sensitive to darker colors, so it was also a kind of proto-compression.
    This is the #1 mistake of programmers, who work with colors - it has even snuck in a common software, like browsers. If you mix two RGB values, you should always square them first, mix, and then sqare root them.
    * To be exact, they are not even square roots, they are 2.2-degree roots.

    I've heard claims floating around that you can see invisible Colors by abusing the fact that when neurons fire too often their outputs are ignored by the brain. The idea is, for example for hyper green you can stare at a red image for a long time until the neurons that carry short cone information are deactivated and then quickly switch to a green image while those neurons are still deactivated and that will let you see hyper green but I don't know how true it is

You will find some people will agree with your interpretation and some won't. Only listen to opinions that are based on emotion if they come from people whose emotions are more important than your own. For them, you can state, "With limited exceptions, this is the truth" and continue to think the way you do now. If people argue with you and they have numbers rather than emotions on their side, be open to what they say and let it percolate in your mind. You get to choose whether your opinion has changed, remains the same, or is enhanced based on what you recently learned.

    This is an excellent introduction to color math! I would love to see a part 2 to this as well, covering things like Color Rendering Index (CRI), perceptual color spaces (CIELAB, HSLuv, etc), and the different types of colorblindness. Colorblindness especially is something that's often misunderstood as a complete lack of color-processing ability, where in the most common forms just have a slight shift in the response curves for M cones (as in deuteranomaly) or L cones (as in protanomaly) so they overlap way more -- effectively, making the red-to-green side of the chromaticity chart "shorter".

  • @MrApolloTom
    @MrApolloTom 2 роки тому +17

    A really excellent video. As a painter I would like to add a bit about subtractive mixing.
    C, M, and Y are a good compromise set of primary subtractive colours but don't really make the definitive three primaries in the same way that additive primaries do. One reason is that when they're mixed, there's a loss of saturation, so while you can make a version of every hue with CMY, you can't mix every colour at full saturation. For this reason painters will often choose different primaries in their palette. With orangy red and a yellow you can make a more saturated range of oranges, but won't be able to make a strong purple with the red. With magenta, yellow, and an ultramarine blue you can make a better range of strong purples than CMY but only a duller orange or turquoise.
    The second issue with subtractive mixing is that you get the wavelengths that the two primaries share in common. If you had a hypothetical red pigment that reflected a pure red wavelength only, and an equivalent blue, they would mix to black! But you could have a red and a blue that look exactly the same to the eye, but that reflect more of a mix of wavelenths. These would mix to a purple of some sort. The conclusion is you can't predict exactly how subtractive pigments will mix just by their visual appearance!
    Thanks and best wishes, Tom

    • @user4241
      @user4241 Рік тому

      In theory, mixing CMY pigments shouldn't make the colors loose saturation. In practice and in my experience (with my printer, lol) blues and greens usually loose saturation, but reds and pinks are excellent.
      It would be interesting to see the result of mixing high-purity cyan, magenta, and yelllow pigments.

    Corrections/Clarifications
    1. 37:10 I misspoke and said m1 instead of m2. What is shown on screen is correct.
    2. 22:12 On screen it says λ = f/c, but this is wrong. The correct formula is λ = c/f.
    3. A common question: Why does a spectral violet (~410 nm) appear slightly reddish, when it's only the short cones that are active? Shouldn't it appear the same as a pure spectral blue (~440 nm)? I have been told by several commenters that the responsivity function for the long cones has a very small secondary peak around the shorter wavelengths like violet. However, I have found conflicting information on this. Either way though, the way that the brain makes colors is very complicated, involving something called the opponent process.
    en.wikipedia.org/wiki/Opponent_process
    The reason this makes spectral violet appear slightly reddish can be found here:
    en.wikipedia.org/wiki/Violet_(color)#Optics
    4. It is possible for some people to see impossible colors by staring at a single color in order to "tire out" one of the cone types. Then, when you look at a different color, some of the cones don't activate like they usually do, because they're "worn out" so to speak. The effect only lasts a few seconds. But be warned, you should never try this with bright lights. They can do permanent damage. More information can be found here:
    en.wikipedia.org/wiki/Impossible_color
    5. In the video, I never explicitly mentioned it, but the Arabs discovered all that stuff about optics way before Newton did. Notably Alhazan en.wikipedia.org/wiki/Ibn_al-Haytham#Book_of_Optics

    • @Tynach
      @Tynach Рік тому +1

      That answer about violet looking reddish is false, there is no secondary bump for 'L' cones. I wrote a more detailed response to that here:
      ua-cam.com/video/gnUYoQ1pwes/v-deo.html&lc=UgxVyExreeBhb3pmFzt4AaABAg.9v-8BLkdGCE9vDkqZQuMJB
      The true answer, is that the color you would see if you were to somehow stimulate each of the three cone types separately without the other, is not what people think those colors would be. The closest colors in the sRGB gamut, while still preserving the correct hue, would be (in hexadecimal color code form):
      L: FF0057
      M: 00FFD9
      S: 7E00FF
      Though, that's using sRGB chromaticities as they are, but using cone spectral sensitivities that are newer than the curves used to measure the sRGB parameters. That is, I used the CVRL's LMS→XYZ matrix to calculate the colors for the LMS primaries.
      If I use an older (but sensibly calculated and considered to be fairly accurate) LMS→XYZ matrix such as the 'Hunt-Pointer-Estevez' one, we get:
      L: FF0074
      M: 00FFD2
      S: 8A00FF
      These values are only correct for sRGB displays, though. And honestly, I didn't bust out my calculator and whatnot, but used some GLSL shaders I wrote a while back; if my GPU is approximating any of the calculations, they'll be somewhat off. Still, they should be more or less reasonable approximations for the hues of the cones' "primary colors".

    This is single handedly the best, most robust, comprehensive and informative video about colors in all of the internet! I hate that the algorithm took 10 freaking months to bring this to my feed! I was geeking out throughout the whole thing. The marriage of the topics of arts (color), physics (waves), biology (perception), chemistry (pigments), astronomy (stars), computer science (hex & HSV) and math has never been this seamless and well connected in any video I've encountered. It clearly shows how much you yourself have been intrigued in these topics and how much you've thought about the relationships between it all, and as someone with shared interests, I literally turned into the neuron activation and pointing rick dalton memes every other minute.
    Not only that, but every time you went onto a small tangent, you made sure to sprinkle in a "well, no, actually" and proceeded to make the viewers informed about the intricacies of the tangent instead of simplifying it too much and moving on. (For example, fact about responsivity and normalized was new to me. And also Newton taking a dumb liberty + supernumerary bands forming purple. And also how Sun's spectrum isn't ideal due to non-uniformly traveling light.)
    Absolutely outstanding job!
    If I were to provide some suggestions, the first would be at about 11:45 where you start introducing colors (purple) outside the curve. You could've sprinkled in stuff like how the light waves, the conversion of light to signals, and the interpretation of signals to color are independent phenomena. Meaning, the brain doesn't care whether it is sensing 'light', but only that it's receiving some kind of 'signal' about the environment. Consequently, if the brain is receiving a signal that peaks at the short and long cones, it will find a way to interpret that as well. But how would the eye even manage to sense receive light that simultaneously triggers both cones if all the wavelengths in the visible spectrum only trigger colors in the curve? And the answer to that would your explanation for monochromatic and polychromatic light. I think it would be a great transitional segment to your excellent presentation.
    There's nothing wrong with your explanation. It's just that as someone who has studied this topic, I can fill in the gaps with my own knowledge, but a beginner might not. I think it would be cool to let viewers know that not only are colors non-existent/imaginative in nature, but also that the color purple quite literally doesn't even exist! Like, it's not even an interpretation of wavelengths by the brain but something the brain just made up! *cue exploding brain*
    The second suggestion would be at 30:10 where you brush over the luminance part. I am personally not well-informed about the details in this specific part, so I just accepted it as is. A bit more could've been nice. And also about how light polarization is utilized in LEDs.

      LED does not need to utilise polarisation, LCD does. In a short version you could say it is a bastardisation of subtractive and additive colours.. 🤔
      An LCD works by shining white light through a liquid crystal, and because of the polarisation that is applied by that sub pixels value it will be blocked by the fixed polarisation filter.
      A fun thing to do if you have such eye glasses you can remove the filter from a display and other people will just see more or less that you stare at a pure white screen

    Excellent analysis of chromaticity and RGB color theory, which explains the physiological response of the eye to visible light. For your next project, I'd suggest an exploration of Opponent Color Theory, which explains the brain's psychological response to color and the phenomenon of metamericism. Briefly, the optic nerves between the eye and brain combine the RGB components from the cone cells into sum and difference vectors which the brain interprets as a pair of orthogonal color axes: a red-green axis and a yellow-blue axis. Each distinct area of color in the visual field is mapped into a position on each axis according to its chromaticity relative to its perceived background. These two-axis coordinates are interpreted by the brain as the metamerical hue of each perceived area of the visual field. Opponent color theory explains how different RGB combinations can produce the perception of the same psychological hue. Also why we can perceive shades such as greenish-blue and reddish-purple, but not yellowish-blue or greenish-red.

    This was a really good explanation. You deserve way more views on this video. I studied Physics but have recently started trying to learn to paint, and I think for this reason the UA-cam algorithm recommended me your video. And it was actually exactly what I wanted, without even knowing I was looking for it. An easy to understand but mathematically vigorous explanation of colour. I actually can't believe this video was suggested to me, it has been so useful!

    This is one of my favourite video essays on UA-cam. I have shared this with many of my friends, which is a testament to how well you walk the balance between "simple enough to be accessible" and "informative enough to have something to offer to people from a range of backgrounds (i.e. my physicist friend and my artist friend both learned stuff)". That's a difficult balance, well done

    Great video! I'll add one thing I discovered while looking into colors: painters refer to a color mixed with white a "tint" (e.g. ice, mint, ivory, etc. in the diagram), with gray a "tone", and with black a "shade" (e.g. navy, burgundy, pine, etc. in the diagram). They can be useful when designing a color scheme.

    The way you explained chromaticity was absolutely eye-opening. I have seen many explanations but all of them left me a bit confused in the past. TURNS OUT you actually get the concept of chromaticity by first understanding what luminance is -and then it just follows that chromaticity is just lines pointing to the origin in the color space.
    I've dug around on Wikipedia before curiously reading about pretty much the same topics you've explained on this video yet I've never seen such a full explanation. I finally understand everything. This was such a great video, keep up the good work!

    I have been thinking about colors and have a lot of un answered questions about them for a long time, until now. This is probably the best video about colors I ever seen, and probably the best will I ever see in the future due to the fact that 90% of the questions got answered in a single video by explaining natural phenomenons like scattering of lights in sky and emission spectrum of discharge tubes, and by also going into different branches of science such as biology, cosmology and quantum mechanics.

  • @murraypearson2359

    This video is astonishing. In addition to being a bona fide colour expert (a journeyman pre-press technician since the 1990s), I have a solid background in physics and quantum mechanics. And yet, I don't think there was s single minute in this video in which I did not learn something new, or clear up a misconception that I have carried for a long time. Bravo!

    • @murraypearson2359
      @murraypearson2359 2 роки тому +1

      Here's a discovery I made about real-world subtractive colour, which astonished me. After a long time in prepress, I decided to empirically determine the ratio of CMY that will make a (horrifically unstable) neutral grey. I expected some weird combination of arbitrary-looking percentages that would be not obvious at all, so imagine my surprise when, after long long experimentation, I concluded that 40%C, 30%M, 20%Y is DEAD NEUTRAL. It's so accurate that I began inserting 40/30/20 patches in dead space on press sheets (gang printed cards of all sorts) and told the pressman to make those neutral grey. Hey presto, reliable on-press CMYK calibration, it saved my employer a ton of money in avoided reprints for bad colour.

    @Cubinator73 2 роки тому +2

    This video is a picture-perfect example of an educational video that is absolutely packed with good explanations and visuals backing them up, and without going overboard into the realm of "abstract nonsense", hats off :)
    Also, as a passionate coder and photo and video editor I've always been interested in how editing software processes colors (beyond the typical "every pixel is an RGB/YUV vector") and how color spaces "work" (beyond the knowledge that they are just ways to assign numbers to colors). And even though I can handle all kinds of color transformations in the software I use, I never really "understood" them, and I never really found articles with sufficiently detailed AND intuitive explanations behind the ideas in color theory. Most of them just simplify stuff beyond ELIM5 and others just go headfirst into linear transformations without first giving an intuition of why the theory we are looking at is linear in the first place. And when it comes to the CIE chromaticity diagram, all articles I found are math-only articles without the slightest intuitive explanation.
    I had a real aha-moment when I saw the emission spectrum of a 3000K star together with the boundary lines for the visible spectrum and instantly thought "that's why hot stars look blue rather than orange/white!" before you even went on to explain why hot stars look blue. And for some reason I just had to laugh when I heard "[...] results in the light emitting diode emitting light" :D
    This video answered all the questions I ever had about color spaces, and this video is exactly what I wish all educational content aimed at a general audience would look like :)

    This was such a good video 🥲 love how you actually went (somewhat) into each topic you covered instead of straying away from the nonessential stuff. Some people might like the more “focused” kind of video, but I thought you did a great job of visiting a bunch of different topics but still keeping it unified
