Rzewuski describes the Kuhaylan (Kohlan) as having black skin and a thin coat with many bare areas, and that the name derives from Kohl. The bedouin horse is not a tall horse. There is much description of coat color variation, seen more in the desert than elsewhere. There are descriptions of colors, lists of strain names and the origins of the strains. Thanks to Kate McLachlan for sending us the articles and Michael Bowling for the overview.
