no he is considerd a GRAY horse if the horses skin is black than it is gray if i could i would go get the horse who was shadowfax and shave his coat than the skin would be black and the coat color is white but he is a GRAY horse i ve been riding horses since the 1st grade (now almost 15) i should know
i ve noticed that to but that is because the horse has a marking there if the nose was all pink than thats albino but little sploches are markings and the yellow mane doesnt mean any thing and ive seen a gray horse with a yellow mane there are many dif types of gray horses but this is very confusing to explain so never mind
no see he is always a gray horse but his COAT is always white but if you went to look at different types of gray horses than there are 3 i think a dapple grey with a gray coat and little round spots of white, and a flea bitten gray with a white coat and little spots of brown that look like flea bites, and a regular gray that is all white i know its very confusing but hopfuly i answered your question
