Is there such a thing as black bay? I've heard and seen it mentioned but I can't seem to find anything on it. My new gelding is supposedly black bay, in his winter coat he is pitch black (except for some sunbleached hair and his white markings) so he's definitely not brown. But in the summer he starts looking like a bay, I'm thinking maybe that's why they called him black bay? I was thinking it could just be sun bleaching. He is the one in my avatar.
