Have you heard about the rare white Thoroughbreds? Out of 30,000 Thoroughbreds that are registered in the Jockey Club, 64 are registered white! The most exspensive weanling of the day in a Thoroughbred auction was a white one and he sold for $80,000! I want one! :)
They're actually not cremello or albino (there's no such thing as an albino horse), white Thoroughbreds are really extreme sabinos. Since they're bred for their color, they unfortunately usually aren't very good racehorses, but they are very pretty.
