Palomino is the color of Gender on a horse, consisting of a golden mantle and a white mane and tail. Genetically, the palomino color is made by a single allele of dilution genes called cream genes that work on the "red" (chestnut) base layer. Palominoes are created by the genetic mechanisms of incomplete dominance, therefore they are not considered to be genuine breeding. However, most of the registrations breed the color that records the horses' palominoes established before the color genetics of the horse's coat are understood as well as they are today, because the standard definition of palomino is based on visible fur colors, not the heritability or underlying existence of the gene dilution.
Due to their different colors, palominos stand out in the show rings, and are much sought after as parade horse. They were very popular in movies and television during the 1940s and 1950s. One of the most notorious palomino horses is Trigger, known as the "smartest horse in the film", a loyal mountain of Hollywood cowboy star Roy Rogers. Another famous palomino is Mister Ed (real name Bamboo Harvester) who starred in her own TV show in the 1960s.

Description
Palomino horse has a yellow or gold coat, with white white mane and light mane and tail. Shades of body coat colors range from cream to dark gold.
Unless also influenced by other unrelated genes, palominos have dark skin and brown eyes, although some may be born with pink skin that darkens with age. Some have slightly lighter brown or yellow eyes. A heterozygous (CR) -like cream like palomino should not be confused with a horse carrying champagne fluid. Champagne (CH) champagne is born with pink pumpkin skin and blue eyes, which are dark within days to yellow, green or light brown, and their skin gets darker dark skin around the eyes, snout, and genitals when the animal is ripe.
A horse with pink skin and blue eyes in adulthood most often is cremello or perlino, a horse carrying two genes of cream dilution.
The presence of soot gene can result in palomino having dark hair on the mane, the tail and the mantle. The palomino summer coat is usually a bit darker than the winter coat.

Color confused with palomino
Many non-palominos may also have a gold or brown coat and a lightweight mane and tail.
- Chestnuts with hemp and tail leaves: Light chestnuts with light creamy mane and tail carry flaxen genes, but not dilution creams. For example, the Haflinger breed has many mild chestnuts with flaxen that may superficially resemble dark palominoes, but there is no cream gene in the breed.
- Cremellos carries two copies of the cream genes and has a light mane and tail but also a cream-colored coat, reddish pink skin, and blue eyes.
- Genene champagne is the most imitative palomino, because it creates a golden layer on some horses, but gold champagne has bright skin with freckles, blue eyes at birth, and amber or hazel eyes in adulthood.
- Horses with very dark brown coats but manes and yellow tails are sometimes called "brown palominoes," and some palomino color registrars accept horses of that color. However, this staining is not genetically palomino. There are two main ways colors are created. The most famous is chestnut liver with hemp leaves and tail. Genetics that create hemp and light tails on chestnut horses are not yet fully understood, but they are not the same as cream dilution. Other genetic mechanisms come from the silver dapple genes, which brighten the dark coat to dark brown, and affect the mane and tail even stronger, thinning into cream or almost white.
- The Buckskins have a golden body coat but black mane and tail. Buckskin is also created by the action of a single cream gene, but in the mantle of the bay.
- Dun horses have tan bodies with darker manes and tails plus primitive marks such as the lower back line of the spine and horizontal striping on the upper back of the forearm.
- The homozygous pearl gene creates an apricot colored layer with pale skin. When crossed with a single cream gene, the resulting horse, often called "pseudo-double-dilute", appears visually to cremello.
Registry multiply colors
In the United States, some palomino horses are classified as color races. However, unlike Appaloosa or Friesian, which is a different breed that also has unique color preferences, Palomino color registrars often receive different types or types if the animal is golden. Palomino can not be a true breed of horses, because the palomino color is a dominant gene that is incomplete and does not breed "right". Palomino crossed with palomino can produce palomino about 50% of the time, but can also produce chestnut (25% probability) or cremello (25% probability). Thus, the palomino is only a partially expressed color allele and not a set of characteristics that make up the "breed."
Since registration as a palomino with a breed color registry is based primarily on the color of the mantle, horses of many breeds or breed combinations may qualify. Some of the breeds that have representatives of Palomino are American Saddlebred, Tennessee Walking Horse, Morgan, and Quarter Horse. The color is quite rare in Thoroughbred, but it actually happens and is recognized by The Jockey Club. Some breeds, such as Haflinger and Arabs, may look like palominoes, but are genetically chestnut with manen and tail lesions, because none of the breeds carry the cream dilution genes. However, despite their lack of DNA cream, some palomino color registrars have listed the horses if their coat colors are within acceptable color range.
While the standard colors used by palomino organizations typically depict ideal body colors such as "newly minted gold coins" (sometimes mistakenly claimed to be pennies), a wider range of body colors are often accepted, ranging from cream-white color to inside, dark chocolate palm ("chocolate palomino") can actually be a silver or chestnut dell with fox and tail feathers.
Requirements for registration
In the United States, there are two primary color breeds registration for Palomino colored horses: Palomino Horse Association (PHA), and Palomino Horse Breeders of America (PHBA).
The Palomino Horse Association (PHA) lists the horses' palomino of type and type "in color and conformation." The color that is considered ideal by PHA is the color of gold coins, but the palomino shades from light to dark gold are accepted. The mane and tail needed to be white, silver, or ivory, but up to 15% dark hair or reddish brown is acceptable. For the sake of palomino horse breeding, PHA also enrolled a full-blown blue-edged kremelo, mistakenly called "cremello palominos" by PHA. Horses that are not recorded by other registry of unknown genealogies are accepted if their color meets the definition of PHA from "palomino."
The Palomino Horse Breeders of America (PHBA) has strict requirements. In order to be accepted by the PHBA, in addition to color, the horse must have a general structure that is compatible with the light-type lighter breeds recognized by the PHBA. Adult PHBA horse height is 14 to 17 hands (56 to 68 inches, 142 to 173 cm), and the horse should not show the concept of a horse or a pony. A person who does not meet altitude requirements is still acceptable if registered with one of the applicants of a breed recognized by the PHBA. PHBAs usually require horses or both parents of horses to be registered by or qualify for registration with a recognized applicant of certain breeds, including those for American Quarter Horse, Paint, Appaloosa, Saddlebred, Morgan, Holsteiner, Arabic, Arab Partners, Pinto (horse division only), Thoroughbred, and various horse race gaited. Horses with parents enrolled in the PHBA also qualify even if they are not recorded with other breed registration. In some situations, horses and gelding can be registered without pedigree only because of their conformation and color alone, but the stallion should always have a genealogy "verifiable factually."
Ideal PHBA body color is the color of "United States gold coins". The mane and tail should be white naturally, and may not have more than 15% black, brown or off-color hair. Primitive marks of brown or dark are not accepted. The PHBA also does not accept horses that are gray or show the color characteristics of Cat, Pintos, Appaloosas or cremellos or perlinos. The skin should be dark, in addition to the pink skin on the face connected to the white mark. The PHBA will not accept a horse for regular registration if it has all three characteristics of a double-dilute cream: light (or pink) skin above the body; white or cream-colored hair â € <â €
