Very true. When I was horse shopping I went to look at a 3 y/o who was still jet black except for his tail, which looked like someone stuck an off-white fake in the bottom half of his tail- nothing else gave a hint that he was graying anywhere else.
ETA- I'd describe him as chestnut or flaxen chestnut for the purposes of an ID card.
