Even experienced horse  people  often believe that Thoroughbreds only exist only in the base colors of bay, chestnut, black, and grey. However, throughout history, we can find evidence of a colored thoroughbred appearing every now and then.  Spotted Thoroughbreds, i.e. overo Thoroughbreds were documented to have occurred as early as the 1700's.

White-splattered chestnut, Airdrie Apache was  the 1993 offspring from the white mare, Not Quite White (1989). Not only  did Airdrie Apache come from a white mare but, overall, his pedigree carries 13 white-producing ancestors: eight doses from The Tetrarch, two more from The Tetrarch's sire, Roi Herode, two counts from Black Toney with the remaining one from Hyperion.

The W-mutation for this family has not yet been identified. His coat allowed him to be double registered as a Paint—a commodity that was  the driving force behind his popularity at stud.

Colored Thoroughbreds are in high demand both here in the U.S. and abroad. The Thoroughbred is one of the only breeds that crosses very well and can be used to refine lines of sports horses to include dressage, eventing, endurance, polo, as well as Western disciplines.  ATO Horses is also integrating racing bloodlines of top Thoroughbred sires and dams to offer breeders and trainers a chance to develop a colored foal for the track.  And while we strive for beautiful colors and patterns, we prioritize conformation, movement, and height.

Thoroughbreds  have a number of white spotting patterns (also called dominant white or extreme sabino).

White spotting (W) is family of spontaneous mutations of the KIT gene--- this is why white horses crop up from seemingly ordinary, solid-colored parents.
