Explain what is meant when we say that the colors in paint are due to the subtractive process.

I don't know...help!

color pigments absorb colors, and reflect what we see. For instance, grass is green because all colors are absorbed, except green.

So color pigments subtract what they absorb. If I put a yellow light on grass, it appears black (no reflected light).
