There are some pink skinned arabians because of the sabino gene. They usually aren't entirely pink skinned with a white coat though, most have atleast a small patch of color with black skin, like on the tip of the ears [medicine hat].

Amy, I do believe that, Raffles was later, either recognized, or had his reg. papers changed to show that he was, for the records, a Grey horse. No, he was not pink skinned. I do believe that there are no pink skinned, or albino Arabians... correct me if I'm wrong...

Is Raffles is the only registered white arabian? I thought arabians could not be white, only grey. Was Raffles truly pink skinned?
