if black is all colors and white is no colors what is gray?

That’s not entirely true. Colour is light. You see colour when light hits your eyes. Light can be emitted, like by a light bulb, or reflected off of objects. Different colours of light are reflected in different proportions by different objects.
Black is what you see when little or no colour hits your eyes. In practice, this means you see black when 1) There’s no light, or 2) Something is reflecting almost none of the light that hits it (aka absorbing all light)
White is the opposite. It’s what happens when all light hits your eyes **at equal strength, and high concentration**. In practice, this means you see white when 1) There’s a lot of all kinds of light, or 2) when something in the environment is reflecting all kinds of light equally.
Now, to answer what Grey is:
Grey is a mix between White and Black. Grey is what happens when something is reflecting all types of light equally, but not in high amounts. It’s literally a darkened white, or a brightened black.
This is why you can’t create what looks like a black or grey coloured lights. It would just be a dull source of white light.
!. I’m assuming we’re speaking about additive light, aka the RGB scale
2. If so, you got it flipped there. Black is no colors, white is all colors
3. RGB works by having different amounts of each color in a scale of 255. Having a scale of 255 for red but 0 for blue and green will give you the color red. Having red at 255 and green at 255 but blue at 0 will give you yellow. All color combos fall into this system. When the numbers for red, green, and blue are the same and aren’t 255 or 0, you get shades of grey. (EX: R:147 G:147 B:147, which is a mid-tone grey)
Search up color picker on google, you’ll get to play around with the colors and see the different combos 🙂
We have values for each color, 0 – 256, back is all the lights off, white is all the lights on. Grey is each color equally, but not all the way. Like there is one color gray. There isn’t even one way too spell it, 256 shades of grey. I guess it’s a gray area
That’s backwards, dear.
But paint and light are different substances. Light is energy and paint is minerals mixed with liquid.
Gray is a hue. Google advanced color palettes and then look up light refraction
All colors is brownish-gray. Black is generally one pigment(charcoal or bitumin derivatives). White is almost always one pigment(titanium, aluminum or formally lead oxide).
It gets more complicated than that but this is ELI5
An important thing to remember is that color is mostly psychological. Our eyes have sensors that detect a very specific range of the electromagnetic spectrum, and our brains interpret those signals as colors.
We have three types of cones in our eyes that sense three different ranges of wavelengths of light. *Very approximately* speaking, you can say that we have red, green, and blue sensors in our eyes. And our brains interpret different combinations of those signals as colors. If our blue and red sensors are most stimulated, our brain says, “That’s purple!” If our red and green sensors are stimulated, “That’s yellow!”
And if all of our sensors are about equally stimulated? Well, that’s no color. If there’s no color and it’s dark (not a lot of light hitting our eyes) then it’s black. If there’s no color and it’s bright (a lot of light hitting out eyes) then it’s white. Somewhere in between is gray.
White is all colors, and black is also all colors, but white is reflecting all colors, and black is absorbing all colors. Grays are different intensities of reflecting all colors. This has a specific practical use in photography where we use “gray cards”, which are specifically made to reflect exactly 18% amount of the light that hits it because that’s the standard which light meters are rated to.
“ I am Grey. I stand between the candle and the star. We are Grey. We stand between the darkness and the light.”
Black is the absence of color, white is the mixture of all colors gray is white and black mixed on a gradient.. it is the transition between black and white.
That has to do with relative and total intensity.
Lets say you have a white ball and you shine white light on it. It doesn’t absorb any of the light and so all of the colors bounce off and can be detected by your eyes.
Alright, now lets cover the ball in paint that absorbs 100% of all colors except red. That means all of the greens and blues (and everything in between) are absorbed and only red light bounces off into your eyes so the ball looks red.
Okay, but what if the paint only absorbed 50% of the greens and blues (and, again, everything in between)? The ball would appear pink (or as Donut from Red Vs Blue would say, “Light-ish red!).
Lets extend that to black: if we cover the ball in paint that absorbs 100% of all colors, the ball would appear black.
But, if we covered it in paint that absorbed only 50% of all colors, it would appear gray because all of the colors would be reflected to your eyes with the same ***relative*** intensity but at only ~50% the ***total*** intensity.
