The white coat of the horse is in the field of hippologie, a horse coat color, characterized by a completely white coat without any stain or mark, a uniformly pink skin and blue or dark eyes. Geneticists, including Americans, put forward several explanations for the origin of the white dress in horses. The gene, named "W" is not clearly identified. The white dress is extremely rare and may appear spontaneously in a foal from a normally colored horse population, probably by mutation. A horse race is exclusively featured on this color, Camarillo white. The white coat can be obtained by crossing two overo horses between them, but it is then associated with a serious genetic disease, white foal syndrome, which causes death of the foal a few hours after birth.
The white horse, known scientifically since relatively recently, has always been at the origin of myths, legends, tales and rituals in human culture.
