@freemo I want to say black because it absorbs light but polar bears are white and they seem like they know what they're doing.
@valleyforge Polar bear's skin attached.
But yea the polar bears black/white combo might actually be a clue for you if you think it through.
facetious answer
@freemo
White clothes are better camouflage in a snowy environment. Getting killed by a polar bear would cause your body temperature to drop to ambient; thus white clothes are an advantage for staying warm.
