What color is a polar bear’s fur?

Polar bear fur is colorless and transparent. In fact, the hair shafts of the polar bear's down and outer coat are very special. They are colorless, rather than white or transparent. A polar bear's downy hair keeps it warm in arctic environments, and its long hair protects their skin from moisture loss. Although polar bears' skin is usually black, the special structure of their hair gives them a white or yellow appearance. In summer, their long hair will shed in large quantities and the density of their hair will decrease to adapt to higher temperatures.
