Chlorophyll just absorbs blue and red light; it hardly absorbs any green light at all, so the green gets reflected back to our eyes, which is why leaves appear green. Other pigments that plants have in their leaves absorb light of different colors, so they reflect red, orange, yellow, or blue light and appear to be those colors to our eyes.
Each primary color of paint absorbs one primary color of light. The color absorbed by a primary color of paint is the complementary color of that paint. The three colors that are primary to an artist (magenta, cyan, and yellow) subtract red, green, and blue individually from an otherwise white sheet of paper. Magenta paints absorb green light. Cyan paints absorb red light.
