Equine coat color

Horses show different colors and different marks. A special vocabulary has evolved to describe it.

While most horses have the same color throughout life, some, over several years, will develop a different coat color from which they were born. Most white marks are present at birth, and the basic horse's skin color does not change, there is no illness.

The basic outline of the genetic color of horse skin has largely been resolved, and DNA testing to determine the possibility that the horse will have offspring of a given color has been developed for multiple colors. Discussion, research, and even controversy continue on some details, especially those that surround the pattern of spotting, sub-color colors such as "soot" or "hemp", and marks.

Basic base color

Genetically, all horses start out as chestnut, called "red" by geneticists, represented by the absence of an extension gene ("e"); or black based on the existence of the extension gene ("E"). Therefore, red ("ee") and black ("EE" or "Ee") are the two basic colors. Bay colors are expressed when a common genetic converter, the Agouti gene, works in black. The wide range of all other feather colors is created by the action of an additional gene in one of these three feather colors.

White signs are present at birth and are unique to each horse, making them useful in identifying individual animals. Marking usually has pink skin underneath, although some signs may be absent, and white hair may extend beyond the underlying pink area. Although the signs covering dark skin may appear to change, skin tone and hair growing from pink skin will not change. Horses can also be uniquely identified with unusual eye colors, circles, brands and chestnuts.

Breed colors

The registry has been opened that accepts horses (and sometimes horses and mules) of almost any breed or type, with good colors the only requirement for registration or key criteria. This is called "race of color". Unlike "true" horse breeds, there are some if any unique physical characteristics are required, as well as stud studs that are restricted to only certain offspring or horse breeds previously listed. As a general rule, color also does not always multiply (in some cases, due to genetic impossibility), and deceased descendants are usually not eligible to record with color breeding registries. The best known breed color registry is for buckskins, palominos, and pintos.

Some "true" breeds also have a color that usually breeds as well as distinctive physical characteristics and limited stud books. These horses are true breeds that are said to have "color preference". They are not descendants of color, and include Friesian horses (must be black uniforms for primary registration), Appaloosa (Leopard or other Leopard complex patterns) and American Paint Horse. In some breeds, though not all, offspring of animals enrolled in these stud books can also be registered, sometimes with restrictions, even if they do not have the desired color.
