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?)
