>> Plant leaves, for example, reflect green light even if there are no eyes to see it

It seems that the logical colour for a leaf would be completely black - absorbing all energy. Fortunately that isn't how it worked out.

Well then leaves would get too hot and plants can’t absorb unlimited sun

They need to absorb red and blue light

Right but Dyson sphere isn't green I don't think.

To be fair unlike the Dyson sphere, leaves actually exist

What I mean is capturing all energy from the sun seems ideal from an energy perspective. If you can prove that green is ideal, great. If not, what are you saying? Just that most leaves are green?

If we assume that absorbing green light comes at a cost to absorbing other spectra, the it very well could be that also absorbing green light would lead to less usable energy absorbed.

At least thats my assumption on why planta dont absorb green.

Dyson spheres aren't real.

Under a thick canopy it basically is like that.

That would be true for mirror leaves as well.
