It still doesn't explain the need to reflect green, though. They could have evolved to be black and absorb all energy.

Well I think the question then becomes can they use that much energy without cooking themselves alive? Maybe the entire spectrum is simply too much incoming energy to dissipate effectively and blue and red absorption are either more efficient or is easier to accomplish than green.
One, you're adding intent to a process that has no intent.
It's not reflected- it's just not used (and thus absorbed). If the plant has more energy that it needs already to produce offspring... what pressures exist to produce more?
It is reflected. That's why plants are green.
You seem to have missed the context of my reply:
> an extinction level event that filtered sunlight for a long time, removing green
The lack of green sunlight would not necessarily result in a mutation that reflects green. There is no evolutionary pressure for reflecting/not using something that doesn't exist. In fact, it would be adding intent to a process that has no intent.
