Colour Changing Fur Coat

Warmer colours in Winter and Cooler in Summer

Siamese cats and Himalayan rabbits have a gene mutation (see Link) which causes a gradual colour shift when subjected to a change of ambient temperature. In a nutshell, they turn darker and fortuitously more heat-absorbing when temperatures drop and turn lighter and more heat-reflecting when temperatures rise. This partially explains why a Siamese's ears, tail and other extremities are darker than the rest of the body.

I propose utilizing this feature in designing a range of fur coats which adapt to keep the wearer at a comfortable temperature over a wider range of the year. To more sensitive readers, I suggest that the manufacturing method should be my Cruelty Free Fur Coat idea (Link) but I will leave it to [8th of 7] to propose more pragmatic alternatives.

       Hmmm, p'raps that WOULD pose a few difficulties to the seamstress. Either that, or it will necessitate the inclusion of a lot of extra plumbing for nutrient supplies to the inner lining of the garment. In any case, all manufacturing processes can expect to face some sort of technical challenges.

       In that case, shedding may be a problem, but at least stains would dissapear after a while.

       So, it's basically a Global Hypercolour coat then.
