Where did buckskin come from?

Answer 1

If you mean Buckskin the horse color, then it came about through the cream dilution gene acting on a bay or black horse. The cream gene affects the body color of the horse giving it a 'washed out' appearance. In the single form cream will not typically affect the black coloring on a bay horse leaving the points dark, but will dilute the body color. In it's double form Cream will usually affect the black points as well.
