  • Color is a property that belongs to light (i.e. electromagnetic waves). We only think objects are colored because of the light they reflect and scatter. In fact, some of the colors you see are an illusion created by your eyes and brain. What colors are real and which ones are fake? Let's find out.

      No, no, no! Explain to them that there are different colors and different experiences with colors, not that a red apple is actually not red and does not even have a color, and that white is not a color. Teach them some good science about light, enough to make the work of a visual artist easier.

      @@AlleyKatt Every artist, at least since the renaissance, has known about primary and secondary colors even if they did not know about the light sensors in our eyes. I am pretty sure that no artist has ever thought "white is not a color, the red apple in fact has no color either, I will use this in my painting". I would like to play with holograms and lasers to make images that different people see differently, but I would still be using objects that have a property called "color", and I would still be using combinations of different wavelengths that are, by definition and by physics and by anatomy, a color.
      There is a lot of physics and biology and optics that you can learn, much more than what was presented poorly here, and it can be used by artists and scientists in several ways, but just redefining words is not the way.

      And that title is equally clickbaity and wrong. Color is by definition a perception, *not* a physical property of light. His statement at 2:37 is only half true: technically, neither objects *nor* light have color. Even Sir Isaac Newton already knew this and wrote "Indeed rays [of light], properly expressed, are not coloured. In them there is nothing else than a certain power or disposition to stir up a sensation of this or that colour."
      On the physical side, you have reflection or emission spectra, but not color. Colors are a perception, and therefore are subjective and depend on context. Meaning that physically identical spectra can be perceived as different colors. There are many optical "illusions" that demonstrate this, such as the checker shadow illusion, or that infamous black/blue white/gold dress. And conversely, different physical spectra can be perceived as the same color. Yellow is a simple example for that (spectral i.e. single wavelength yellow vs. yellow made from red + green - physically different, but perceptually identical, and therefore the same color).

      I think I heard that the red cones have a second response peak at wavelengths shorter than the blue cones' peak (they fire at "violet", but not at the longer wavelengths of indigo blue), which is why the spectrum looks like it maps onto a color wheel despite not looping.
      And as Nick described, an RGB display has three colored lights in each pixel so those mostly aren't spectral colors, either.

  • @iamamcnea
    @iamamcnea 5 лет назад +4

    I would say wavelength is a property of light. Color is an emergent property of consciousness. Although color does correlate with wavelength often, that's not a requirement. From that standpoint the color white or magenta is just as valid as the color red.

    • @tom_something
      @tom_something 5 лет назад

      That seems fair. Dark red and bright red are just different preceived magnitudes of the same wavelength, identified as distinct colors from one another. And pale yellow is what happens when our eyes get the same recipe as plain yellow, with a little bit of blue in the mix. Of course, if we strip value (or brightness) and saturation out of the mix, we're left with just hues. Which almost correspond to wavelengths, except for that dastardly magenta.
      So then, can we say that since color is not a property of light, objects _can_ have color? I guess we still have to say that they can't, since, as demonstrated in the video, the color of an object is perceived differently depending on the light that it is exposed to. And that goes outside of the visible spectrum, even. Something that appears to be mostly white in visible light may emit bright blue light when exposed to ultraviolet light. Is it blue when that is happening? Is it sill blue if we're not looking at it?
      So yeah, I guess color is not a property of matter or of light. Colors are purely the product of perception. Or.... frame of reference?

    • @iamamcnea
      @iamamcnea 5 лет назад

      @@tom_something Yep, I would say color is purely perception. For instance people will tend to see flashes of colors in a sensory deprivation tank, or on hallucinogenic drugs. There need not be matter nor light in order to perceive color (although these cases are the outliers to our day to day experiences).

    • @tom_something
      @tom_something 5 лет назад

      @@iamamcnea There's a sort of color theory whereby the input from our three cone types then goes through an intermediate processing step. In this step, there's sort of an x-y plot. One axis goes from blue to yellow. The other axis, some say it goes from green to red, others say it goes from green to magenta. And the midpoint on each scale is basically an absence of color. So there's not really a way for us to perceive bluish yellow or greenish red. They're not colors, simply because our brains decided not to make them into colors.
      It could have been a blue-to-green scale and a red-to-yellow scale instead, but it isn't. We just... didn't do that.

    One thing your LCD explanation missed: because each of the three primary colors actually stimulate all three cones (especially green), some combinations of "signals sent to the brain" are not possible to reproduce using an RGB LCD (the commonly cited one is "deep orange"). If you look at a chromaticity diagram, the colors reproducible using RGB are actually less than half the entire chart.
    This is different from your "this is not actually yellow" because the actual and reproduced color are distinguishable, unlike "pure" vs. "red+green" yellow (this last fact is actually used in a color-blindness test called an "anomaloscope")

      I am a bit late to the party... but You are true. Nick completely omitted "color gamut", even if it is a simple thing to explain - how our brain interprets the impulses from our eyes. With it it would be even more obvious that RGB cannot display "all colors" and that adding more colors isn't "a total and complete waste of your money". Heck, it is even clear from his speaking in the lines of "these three neural impulses are enough" (ignoring rod cells and its - albeit little - contribution to color perception), but clearly showing that e. g. "green" color in LCD screen fires the "red" cone also (and vice versa). Thus we cannot get many "rainbow" colors from RGB screen only.
      Yeah, even white can be a combination of e. g. blue and "clean" yellow, that means only two colors.
      Nick could even speak about materials not only reflecting a particular frequency (e. g. "it is yellow because yellow light gets reflected - its reflected light's frequency peaks at yellow"), but a combination thereof (e. g. "it can also be *perceived* yellow if its reflected light peaks at green and red frequency.." - or whatever color gamut is enabling).
      I've had two bed sheets at home. They looked "blue" the same way (under sunlight, under fluorescent bulb). Still, there was difference. I shone at them with two LED light sources from different manufacturers. One looked the same blue, the other "changed" color to violet. (But both light sources' light cones looked the same when reflected off a white wall.) You cannot explain that without speaking of frequency combinations and gamut....
      I like Nicks videos very much, but I think, he tried to keep it simple... and omitted important facts :(.

      I think that there should be a limit to the continuity of colour dimness maybe there is a defined amount-quantum of light which would be responsible for effective change in perception thus putting a limit to the number of maximum brightness levels per subpixel.
      This may be similar to the case of the frame rate limit in our eyes.

  • @WarrenGarabrandt
    @WarrenGarabrandt 5 лет назад +1

    So, this video is discussing the difference between spectral color (a color that monochromatic light looks like), vs non-spectral colors. There are MANY more non-spectral colors that you see than purely spectral ones because the vast majority of objects do not simply reflect a single wavelength of light. Most (all?) objects reflect more than one wavelength, or reflect a range of wavelength, or there will be enough diffuse light that gets scattered that you perceive it as reflecting that wavelength. Things that appear "Metallic" such as gold and silver, are pretty much impossible for a computer screen to render because they are not made up of any combination of wavelengths by themselves. Since the objects reflect light in different ways depending on the angle of the light, you get a great deal of variation of color over the object, and it takes a very sophisticated simulation to accurately simulate this.
    Just look at diagram of spectral colors and see how limited that is. Now, imagine every shade of grey from white to black. You can mix different spectral colors and shades of grey into millions and millions of combinations and derive WAY more combinations of color than spectral light. For example, 50% blue and 50% red gives a purple looking color. 100% blue and 100% red gives magenta (a very saturated color). You can get pink by mixing a reddish color with white. and brown by mixing an orange color with black or dark grey.
    Oversaturated colors, such as something seeming whiter than white, are possible too, that your monitor has no ability to produce at all. Speaking of impossible colors your monitor can't product: you can mix red and greed, or blue and yellow, in ways that give the appearance of a brand new color, but you get a muddy color not even close to them by using your monitor or even paints.

Color is simply how our brains interpret light. By the way, the human red cone has a small spike in sensitivity in the blue range, which allows up to see purple, if not magenta, light.

    Staring at a bright color will temporarily desensitize the cones associated with that color. Stare at a magenta screen for a while and then change it to green. The green light will no longer activate the red and blue cones as much as it normally would, so you will be looking at a super green color that you don’t normally ever see.

    "We need a source of light, then we need the thing we're trying to see, and then our eyeballs, and then our brains." You just described what we call the "color triangle" at the color science lab I study at. I was thrilled to see it here! I also love how you touch on the idea that objects are not actually colored. Actually, this video is a really great introduction to color science, in general, with a couple of important exceptions.
    First, color is a perception in the brain, not a physical property, which means that your screen DOES show yellow, it just isn't the same combination of light that you would receive from, say, a lemon. This concept is known as "metamerism", if you (or anyone else reading this) are interested in learning more. This is also why any arguments saying "____ is not a color" don't actually make sense. All colors exist only in the mind.
    Second, adding primaries is less about increasing the NUMBER of colors available, and more about increasing the RANGE. Despite popular belief, it is not actually possible to recreate all of the visible colors using only three primaries, and the more primaries that you add, the larger the range of colors that you can see is. Personally, I'm all in favor of adding more primaries to screens.
    Really loved this video!❤ I've taken to watching videos on your channel to understand more about optics and have found it to be an incredible resource.

    @LumenPlacidum 5 лет назад +2

    BUT! The lights that make up the pixels on your LCD screen have to be chosen to emit particular wavelengths of light! This means that, aside from those three very particular locations on the visible light spectrum, your computer screen is TOTALLY INCAPABLE of displaying the other colors that are actually the only colors that physically exist. The subset of colors that is displayable by your LCD computer screen is called the "color gamut" of the screen. If you were to get a screen that has a fourth color of light built into it, then you WOULD actually be able to see additional colors that the screen could not display beforehand. It isn't a total and complete waste of your money. It's just a marginal gain.
    I teach a smattering of this to my Linear Algebra students in high school when we talk about vector spaces. Color gamuts are not vector spaces since it's impossible to generate two colors that will destructively interfere using a computer screen, though. But, there are some really interesting things happening in the science of what colors are perceptible coming from your screen.

      Red and green are less scattered and reach our eyes when we look at the sun. What is red and green combined? Yellow of course. That's why sun looks yellow.
