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

Actually, white contains ALL colors of the color spectrum while black is the absence of light.
White light is presence of all colors. (you see additive color)
Painted surfaces are white light hitting the paint and reflecting only the color you see and absorbing the rest. (you see reflected colors that have not been subtracted/absorbed). The by product of absorption is heat. That is why we paint things white we do not want heated (reflected light) up in the summer and things black (solar panels) that we do.
Black absorbs all color.
White will reflect all color.
Shine a blue light on white paint it will look blue. Because it has only got one color spectrum of light to reflect, change the light to white and it will be white. Reflecting all the colors.
Shine a white light on a blue surface it will be blue. Because that paint color based onthe chemical make up of that paint will absorb everything but the blue spectrum of color and reflect only blue. Change the light to red and that blue surface will look black. Change the light to blue and the surface will look blue.
This is why when you are in a “dark room” with a red light you only see one spectrum of color there is no other light color to reflect but red. Thus everything is either a shade of red or black.
Light is the presence of color. Paint is the reflection of color that is not absorbed. Don’t get me started on glass.
Is it gray or grey? ☺️
Lol all these answers are basically the blind leading the blind. Also its the opposite, black is no color.
Grey is basically just ur mind fucking with you. Its basically an illusion.
What we see as color is just the combination of wavelengths an object reflects. True black reflects no wavelength, this is why no light from sun or anything = everything black/dark. White = reflecting all visible wavelengths.
Grey is actually just white but less intense. Our brain can perceive when its less intense, and preveives this as grey.
The same light waves are hitting ur eyeballs .
Check out this illusion, its because our brain is messing with us when we perceive grey, its just intensity of white, not an actual color.

You can also see this with screen resolutions. Rgb stands for red green blue, and the number up to 255 represents its intensity. rgb(255,255,255) is white, mix the maximum red bkue green, rgb(0,0,0) is black.. no color. Rgb(34,34,34) is a dark grey, its emitting all red green blue equally like white, but less intense. Type into google, rgb(100,100,100) or any combination of all the same number and ule get a shade of grey. Its just different intensities of emitting all wavelengths equally aka white.
White is actually all colors and black is the absence of all colors (black paint is a paint that absorbs all colors of light, because you mixed things that absorb each color).
Grey is just all colors but in moderation. You’ll also find that all blacks and whites that humans produce are technically shades of grey, with “true” black and white being unreachable extremes.
A lot of people say they’re colours and think they’re colours. There’s some fair basis as to why they may think that. However black and white are not actually colours. They are shades.
This is what was taught to me at secondary school around 30 years ago. Adobe seems to pretty much stand by me on this one. They’d probably know best right?
“Some consider white to be a colour, because white light comprises all hues on the visible light spectrum. And many do consider black to be a colour, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colours, they’re shades”

If you’ve never seen one, do a quick image search for what an LCD pixel looks like. What we see as a single point in an image is actually made of “subpixels,” little lights of red and green and blue. They’re so close together, though, that we see the light produced as a single point which is a combination of all three.
These subpixel lights are also dimmable, so they have many brightness settings from OFF to ON. You can replicate a whole range of colors by just varying how much you dim the red, green, and blue in a pixel. Whenever all three are dimmed to the same brightness, we see some shade of gray, including white when all are fully ON and black when all are fully OFF.
So a better way of thinking about it is that black, white, and gray – all three are all the colors. It’s just that white is *all of* all the colors, gray is *some of* all the colors, and black is *none of* all the colors.
Black is the absence of all light and color.
White is the presence of all color.
Gray is a mixture of Black and White; it is everything and nothing. It is perfect (according to the voices in my head.)
