Rose horse: purple, dark brown, light brown, chestnut, chocolate, light chocolate.
Gray horse: dark gray, light gray, white gray.
White horse: pure white or iridescent white, is dominant compared to other pure colors. So when the animal has white markings on a black background or a brown background, the white color seems overwhelming, so the types of horses called white gray, pink white, white dot, white langur may not be very wide on the body, but also often found on the nose, eyelids, lower extremities, mane, tail.
Horses have almost the same color throughout their lives, with only a few changes after years of development to produce a different coat color than when they were originally born. Most are white at birth, and a horse’s underlying skin color will not change. Under the basis of horsehair genetics and with DNA testing to determine how likely a horse will be born with a certain color, the researchers used horsehair color to distinguish the breed.
However, after many years of development, there are some other colors. That is the current issue that is still discussed, researched, and even continue to argue about some details, especially horses with spot patterns, colors such as “sooty” or “flaxen.” Genetically, all horses begin to be born with a chestnut color which geneticists call “red”, due to the absence of the gene (“e”), or the black of the gene ( “E”) flower. Therefore, the red is called gen (“ee”) and black (“EE” or “Ee”) are the two primary colors. In this vast range all other coat colors are generated by the action of gene addition.
The white horse is not born white. At first with black hair then fades to white, normally horse hair turns pure white between about 6-8 years old. The white horse is often referred to as the gray horse because the color changes with an aging process. The horse’s normal skin color is black, the hair is white so we look like it is gray. Many gray horses have discolored skin, some are speckled and some have red streaks called “blood marks”.
