Clydesdales are usually bay in colour, but a Sabino like pattern (currently an untestable KIT mutation), black, grey, and chestnut also occur. Most have white markings, including white on the face, feet, and legs, and occasional body spotting (generally on the lower belly). They also have extensive feathering on their lower legs. Sabino like ticking, body spotting, and extensive white markings are thought to be the result of sabino genetics. Some Clydesdale breeders want white face and leg markings without the spotting on the body.
