I'd suspect a lot of analytics and math when in to determining the exact "color" of the electromatic spectral spectrum. But the brain, the TV, the computer, printing requires additive black, or mixing RGB or CMYK to generate black. Then there is spot black. There are shades of black, usually referred to as percentages of black and white mixed together. Or 100% tiny black dots spaced appropriately over a white background to give the allusion of gray.
So for the sake of this argument, and this beige calculation, let's call it the COLOR of LIGHT, not just color. What say you?
It's all the
COLOR of LIGHT, or rather the way we see light. Without light, there would be no color. Even in
subtractive (reflective) color (
CMYK), the color is the color of light reflected. With color pigments, when you apply a Cyan tint to a surface, you are really applying a filter so that all the red light is absorbed and not reflected. In any case, black is the complete absence of color. In
additive (transmissive) color (
RGB), black is when no light is emitted. In subtractive, no light is reflected. In terms of RGB, black is 000000. There is only one
shade of black, any thing else is just gray scale.
