Sounds very doubtful. I don't know what would trigger an animal fighting for survival to not take an animal because of its coat color.
I hope you're kidding. First of all, not all predators are killed - well, I don't know where you live, but there are plenty of deer killed everyday by wild animals in the United States. Also, how would it benefit the animal to be more visual if there weren't any predators?
