 Even horses with extensive white usually retain dark colored regions just above the hooves, on the knees and hocks, stifles and elbows, hips and points of shoulder, the tail, mane, and the bony parts of the face.The smallest amount of white patterning is just a sprinkling of white over the hips.Just as there is white patterning specifically associated with the leopard complex, there is a type of progressive roaning that is unrelated to graying out or true roan.
