Black is white

Factual Questions
1

Someone just came up with a crazy argument…so crazy it might actually be true.

“Polar bears do not have white fur. It is really black (or at least fairly dark), but the hair shaft is such a shape as to make the fur APPEAR white”

True or false? If true, why?

If false, then I guess my counter-argument was fine.:smiley:

Cheers,
Sparky

A polar bear has almost clear fur. With all the relfection and refraction, it looks white.

The hairs are like clear filaments.
