 Combinations of other white spotting patterns, such as tobiano with heterozygous frame overo, can produce a horse that is 90% white or more.Cremello horses are superficially similar to sabino-whites, however cremellos have blue eyes, rosy-pink skin and a cream-colored rather than white coat.Gray horses have a white hair coat at maturity but unless they also happen to carry dilution, white, or SB1 genes, they do not have pink skin and are not white at birth.
