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

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.
