Splash, or splash white, is theorized to be an incomplete dominant gene. Splash tends to leave white markings with even, well defined edges, almost as if the horse had been dipped in white paint, starting at the the head and legs. Blue eyes are common with splash, as well as bottom heavy or apron blazes. Splash is associated with deafness, but not all splash horses are deaf. It is thought that deafness is caused when splash inhibits pigment production in the inner ear. A well know AQHA stallion that exhibits splash is Colonels Smokin Gun.
