These colors represent good and evil to me. I am a christian and in one of my favorite songs it says that " Jesus will wash me white as snow" and so white represents good and light. and in another song it says "The blackness of the world will be cleansed like a white sheep's fur" so black represents darkness. So Bullet(my pet) is a mixture of both good and evil like the tree of good and evil in the Bible. So since you can't eat of the tree of good and evil it makes you want to pick him more....see where I went with it.
