Bay is the most common horse color. Bay horses can also be further classified into different shades, depending on the intensity of their coat color.
What Colour is a Bay Horse?
Bay horses can have many coat shade variations, with varying intensity of the bay coloring.
Colour variations:
- Standard bay horses: A standard bay horse has a classic reddish-brown coat.
- Light bay horses: The bay coat color is lighter, with a more golden-hued body and prominent black points than the standard bay. Also referred to as a wild bay horse, it can sometimes have primitive markings like dorsal stripes or zebra-type stripes on their legs.
- Blood bay horses: The blood bay has a deeper, dark red, copper-toned shade.
- Dark bay horses: The body color is a deeper, darker version of the bay color. A very dark bay can be mistaken for a black horse.
- Mahogany bay horses: A mahogany bay horse has a darker, reddish-brown coat with very dark shades.
- Seal brown horses: Seal brown bays have a dark brown coat with minimal reddish tones, which can sometimes make them look like solid black horses. However, seal brown horses don’t have the gene that would make them completely black.
- Bay dun horses: These bay horses have a diluted coat color, often with a sandy hue.
- Silver bay horses: Silver bays are the rarest color. Although they aren’t actually silver, they have lighter black manes and tails with black legs. Their bodies are still bay colored.
- Bay roan horses: The bay coloring is blended with grey or white hairs.
Genetics of a Bay Horse
The unique bay coloring comes from specific genes. The agouti gene regulates the distribution of black pigment in the horse’s coat. This results in the signature red-brown body with a black mane, tail, and lower legs.
The combination of the agouti gene and extension gene decides the red and black pigment percentage in the bay horse’s final color.
- Extension gene: Responsible for the presence or absence of red pigment.
- Agouti gene: Restricts black pigment, allowing for bay coloring.
- Interesting note: Bay is a dominant gene, which makes it a common color across most horse breeds.
