Rabicano is a horse coat color that appears to be a type of partial roaning. Horses with the rabicano pattern usually have white hairs intermingled with the base coat color in limited areas, not the entire body. This roan-like effect that is caused by a genetic modifier that creates a mealy, splotchy, or roaning pattern, usually limited to the belly, flanks, legs, or tailhead areas, or any combination thereof. Horses exhibit a diverse array of coat colors and distinctive markings, and a specialized vocabulary has evolved to describe them. ...
