Default Plant-bio question

Not sure how to post a question – but here is one that I have been wondering

Simply – Why are plants green?

I understand about absorption and reflection by photosynthetic pigments but
my real questions is why have plants not evolved abundant molecules that
absorb green light for use in photosynthesis. I know that there are some
plants that have higher levels of anthocyanins and other photosynthetic
flavonoids but why don’t most plants?

Also – If plants did make more complete use of the visible portion of light
– what color would they be? I am guessing more like black or darker shades?
