Answer 1

That is because of, in the case of pigment, the color you see is because the other colors are absorbed. Mixing colors makes it so more colors are absorbed.

Red paint absorbs green light.
Mixing them doesn’t make yellow like it does with light but a merky brown.
Light has colors because it emits that color
Mixing light is like addition. Mixing paint is like subtraction
