I always grew up calling him a chestnut with flaxon mane and tail, though his mane and tail were very light and there was a smidge of black in the center of his tail. I have heard sorel and then there is this silver bay which I know little about. I imagine there should be more on the legs though when he was shed out he was a bit darker on his legs. Especially his knees. I was just wondering what you guys would call him.
