Why trees, mosses, and algae are green??

Why trees, mosses,  even algae are green?

Woow. Thats a great question.
First,  they have chlorophyll on their sell. And, second why chlorophyll is green??

Ok, then. Chlorophyll is a pigmen that caught a photon from sunlight. You know that when you put the sunlight on prism you'll get a rainbow color from the sunlight. So, chlorophyll only absorb a red and blue (violet) rays that rays are needed in photosynthesis reaction. But the the green ray bounced back. That's why leafs, mosses, alga are green.

So, guys that's the reason why are they look green in our eyes.
So, how about the other color? Flowers, wood, or others? So, it depends on what pigmen it has.
