Horses come in a variety of coat patterns and colors. Bay, gray, and chestnut are the most popular colors. Other uncommon colors include roan, palomino, white, cremello, pinto, black, dun, perlino, leopard, and buckskin. Here’s what you need to know about a bay horse.
A bay horse is typically brown, with black points — its lower legs, tail, and mane are black. These horses vary in color shade, from a bright copper red to dark brown that’s almost black (called dark bay, mahogany bay, brown, or black bay). The most popular bay horse pure color is a reddish color known as blood bay.
Genetics of Bay Horses
Equine color genetics studies how parent horses determine the coat color of their foal through gene transfer. The genes that control horse coat colors vary, and they work together to yield specific patterns and colors. Most solid-colored horses display only a few of the said genes, while uniquely spotted or patterned horses may have more of them.
According to horse DNAs, they all have base bodies colored in either black or red (chestnut). The base is the original gene layer. In a bay horse, the second genes (known as agouti genes) regulate the black hair distribution, confining it to only the points and top line. Bays can generally be found in most horse breeds.
Bay colors are in varieties depending on the animal and breed. These are the basic categories.
Mahogany or Dark Bay
Mahogany, or dark bay, is the darkest bay shade. The horse has a deep brown-red body that looks like deep brown or black.
The second darkest bay color, blood bay, is a deep blood-red coat color. The shade looks so much like a shade of purple.
The copper bay is a bright color, with the appearance of a copper penny. The coat color is bright orange-red.
It’s likely the most common shade of bay and what quickly comes to mind when people visualize the color. The body color is deep red — no smutty coloration.
Wildtype bay is technically an actual bay, with black points and a deep red coat. The leg points of a wild bay horse extend to its fetlock or pastern, and this is mostly associated with pangare gene-carrying animals.
Golden or Light Bay
It’s the lightest bay shade. However, the darker shades of bay are more common. The coat can be close to golden yellow or light red.

Since bay is among the most famous horse coat colors, it’s not surprising to learn that several horses have this rich shade.

They’re beautiful English horses and native of the Cleveland District in Yorkshire. Influenced by a mix of Chapman, Andalusian, and Barb horses, these versatile and robust horses influenced several other modern breeds.
The Cleveland Bay breed went almost extinct as a result of many world wars and crossbreeding. But in the seventies, it was restored. Cleveland Bay crosses, and Cleveland Bays are the official coach horses of the Queen of England.
Other Bay Horse Breeds
Most registries approve bay colored horses since it’s a standard color in horse coats. The specific horse breeds that require that a horse must be one color are very few. For instance, Suffolk Punches are strictly chestnut, and Friesians are black. Some horses that have a limited color range are:
Although Clydesdales can have any coat color, Budweiser Clydesdale horses must have a deep bay coat color and fluffy white feet. Specifically bred by Budweiser for their TV commercials and trademark beer wagons, this is the main reason most Clydesdale horses in the United States have bay coat color.
