Why are primary colors different between pigment and light?

Answer 1

Light is additive. You start with black (the absence of light) and the more you have the more you approach white (technically all you need is red green blue)

Pigment is subtractive. You start with white (paper) and the more colors you add the more you approach black. The paint removes light.
