Bay is a standard coat color in horses distinguished by a reddish-brown body and black point coloration on their mane, ear edges, tail, and lower legs. A horse is classified as bay if it has a black base color and it carries the color-modifying Agouti gene. Some bay horses have black points covered with distinctive white areas characterized by pinkish skin.
Bay horses typically vary in color from light copper red to rich blood bay, to dark red called black-bay, mahogany bay, dark bay, or brown. White patterns also occur on bay coat, producing spotted horses with appaloosa-white, paint-white, and roan-white patterns.
Established in 2001, the Chesapeake Bay Horse Show Association organizes horse shows in places around Maryland and Delaware.
