Our stallion, WR Firestorm is a bay. There is also a dark or black bay. This is a horse who has no red in it's coat. The body color is very dark but can still be distinguished from the black mane and tail. Black bays are usually kept stalled during the day to keep their coats from sunburning to a redder color.
Some people mistake black bays for blacks.
All bays always have black manes and tails. Example, Bint Miss Fire is a daughter of Miss Fire. Arabians also can be black. A true black will not have brown hairs on it's muzzle or flanks. Example, Gdanwind is by Gdansk.
