It is a mystery

They are fascinating, and very climate resilient. So many European breeds do very badly in hot weather.

When you've got all those natural colors to work with, it's worth considering -- even if you just do something simple like stripes or block-patchwork. It doesn't have to be as fancy as Fair Isle to look good.

I like the play of natural colors. Plus if you're using a neutral palette in a room or outfit, creating patterns or colorblocks gives it more visual interest. Much as I love bright colors, not everything needs to be dyed to look good.
