why is green photosynthesis so dominant?

I wonder if we could engineer a black plant that could absorb more of the suns energy. A good thing for a science fiction book, one where a nuclear winter blocks the sun or something

It isn't just the color - you'd need a pigment (or set of pigments) that could absorb the frequencies that now reflect and then use those frequencies to feed electrons into photosynthesis. Not just a matter of getting a new color.

Well obviously, what I'm talking about is why don't we engineer plants to contain the black pigment needed to collect more energy...I think you missed my point entirely Anyone else ever heard of something like this? I'm sure someones had to have thought of it before and might even be taking steps to make it a reality. Anyone have any idea why this hasn't naturally evolved in nature?
