Polor bears are not actually white. They appear white because their fur is made up of hollow, transparent, pigment-free hairs, which scatter and reflect light, much the way snow crystals do.
Underneath the fur, a polor bear's skin is black, which is how the animal appears if photographed with film that's sensitive to ultraviolet light.
