LOL, I bet he is, but he's not a true roan. He's either a maximum sabino or dominant white...or maybe there's some LP gene at work there. I don't trust their color descriptors much because they generally wouldn't know their butts from a hole in the ground in that regard. My boy, who is definitely gray, is registered on all his paperwork as a buckskin and he had begun the graying process before he was captured LOL.
It always cracks me up when they have a very obvious bay roan listed as "blue roan" and then not 3 horses down, another bay roan of the same shade is listed as a "red roan" LOL.
