I am interested in learning what those would be called from the genetics experts
I had a BS paint years ago that was a chestnut (out of chestnut parents) that had a palomino colored spot on her upper hind leg near her tail. Wish I had taken some good pictures of it before I sold her. Then I had a palomino gelding with a grey smutty spot on his rear (about the same location as the spot on the totally unrelated chestnut mare). Always made baths interesting, never looked quite clean in that spot. LOL
