Did you know that polar bear’s skin isn’t white? Their skin is actually black. But their fur is transparent and hollow. So, when light strikes the outer fur, some of them is absorbed. As a result, the fur can appear as a different colours in different lighting. Normally they look white because their fur is scattering sunlight. But on a cloudy day they can look slightly grey and at sunset they can appear as reddish orange.
