if black is all colors and white is no colors what is gray?
In: 1072
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.
