Well, I suspect that green fur would make it more difficult for them
(despite no color vision?) to find mates. A fur color that fades too
well into the background would be a mechanism selected _against_.
The rabbit's main advantage is the ability to outpace their predators
in the act of procreation.
And if you think that above is an authoritative answer, I want to know
what you're smoking... :-)
(I just couldn't help the thought that came into mind when I saw this,
given the rabbit rate of reproduction. But it sounds convincing,
doesn't it?)
