Palomino

 ( Horse Coat Colors ) 

• Chestnut with flaxen gene mane and tail: Lighter chestnuts with a light cream mane and tail carry a flaxen gene, but not a cream dilution. For example, the Haflinger horse breed has many light chestnuts with flaxen that may superficially resemble dark palomino, but there is no cream gene in the breed.
• cream gene carry two copies of the cream gene and have a light mane and tail but also a cream-colored hair coat, rosy pink skin and blue eyes.
• The champagne gene is the most similar palomino mimic, as it creates a golden-colored coat on some horses, but golden champagnes have light skin with mottling, blue eyes at birth, and amber or hazel eyes in adulthood."Genetics of Champagne Coloring."

• Horses with a very dark brown coat but a flaxen mane and tail are sometimes called "chocolate palomino", and some palomino color registries accept horses of such color. However, this coloring is not genetically palomino. There are two primary ways the color is created. The best-known is a liver chestnut with a flaxen mane and tail. The genetics that create light flaxen manes and tails on otherwise chestnut horses are not yet fully understood, but they are not the same as the cream dilution. The other genetic mechanism is derived from the silver dapple gene, which lightens a black coat to dark brown, and affects the mane and tail even more strongly, diluting to cream or near-white.The silver dapple gene is not a graying gene. It is a dilution gene which acts only on black pigment.
• Buckskins have a golden body coat but a black mane and tail. Buckskin is also created by the action of a single cream gene, but on a bay coat.
• Dun gene horses have a tan body with a darker mane and tail plus primitive markings such as a dorsal stripe down the spine and horizontal striping on the upper back of the forearm.
• The pearl gene in a homozygous state creates a somewhat apricot-colored coat with pale skin. When crossed with a single cream gene, the resulting horse, often called a "pseudo-double-dilute", appears visually to be a cremello.

Because registration as a palomino with a color breed registry is based primarily on coat color, horses from many breeds or combination of breeds may qualify. Some breeds that have palomino representatives are the American Saddlebred, Tennessee Walking Horse, Morgan horse and Quarter Horse. The color is fairly rare in the Thoroughbred, but does in fact occur and is recognized by The Jockey Club. Some breeds, such as the Haflinger and Arabian horse, may appear to be palomino, but are genetically chestnuts with flaxen manes and tails, as neither breed carries the cream gene. However, in spite of their lack of cream DNA, some palomino color registries have registered such horses if their coat color falls within the acceptable range of shades.

While the color standard used by palomino organizations usually describes the ideal body color as that of a "newly minted gold coin" (sometimes mistakenly claimed to be a penny), a wider a body color range is often accepted, ranging from a cream-white color to a deep, dark, chocolate color ("chocolate palomino") that may actually be silver dapple or liver chestnut with a flaxen mane and tail.

The Palomino Horse Association (PHA) registers palomino horses of any breed and type "on color and conformation". Registration and Membership Instructions Palomino Horse Association Registration and Membership, accessed December 6, 2009 The shade of color considered ideal by the PHA is the color of a gold coin, but shades of palomino from light to dark gold are accepted. The mane and tail are required to be white, silver, or ivory, but up to 15% dark or reddish-brown hair is accepted. In the interest of breeding palomino horses, the PHA also registers full double-dilute blue-eyed cream gene, erroneously called "cremello palominos" by the PHA. Horses that are not recorded by any other registry of unknown pedigree are accepted if their color meets the PHA definition of "palomino".

The Palomino Horse Breeders of America (PHBA) has stricter requirements. To be accepted by the PHBA, in addition to color, a horse must have the general structure appropriate to the breeds of equestrianism type recognized by the PHBA. The adult height of the PHBA horse should be , and the horse must not show draft horse or pony characteristics. An individual that does not meet the height requirements may still be accepted if it is registered in one of the breed registries recognized by the PHBA. The PHBA usually requires horses or both parents of the horse to be registered by or eligible for registration with certain recognized breed registry, including those for the American Quarter Horse, Paint, Appaloosa, Saddlebred, Morgan horse, Holsteiner, Arabian horse, assorted part-Arabian registries, Pinto horse (horse division only), Thoroughbred, and assorted gaited horse breeds. Horses with PHBA-registered parents are also eligible even if they are not recorded with any other breed registry. In some situations, mares and geldings may be registered without pedigree on account of their conformation and color only, but stallions must always have pedigrees that are "verified in fact".

The ideal PHBA body color is the shade of "a United States gold coin". The mane and tail must be naturally white, and may not have more than 15% black, brown or off-colored hairs. Brown or dark primitive markings are not accepted. PHBA also does not accept horses that are gray or show color characteristics of Paints, pintos, Appaloosas or cream gene. The skin must be dark, other than pink skin on the face connected to a white marking. The PHBA will not accept a horse for regular registration if it has all three characteristics of a cream gene: light (or pink) skin over the body; white or cream-colored hair over the body; and eyes of a bluish cast. White markings on the face and legs may not exceed certain limits. Leg white may not be higher than the level of the elbow or the stifle, white on the face may not extend past the throatlatch. Spotting and characteristics of the Leopard complex and the various pinto horse patterns are not accepted, and body spots of less than a 4-inch diameter may be allowed. Horses with non-dark skin on the body, white or creamy coat and pink skin around the eyes are not accepted. Spots of pink skin visible in the muzzle or around the eyes, under the tail and between the hind legs are not accepted. An exception is made for horses registered with the American Saddlebred Horse Association, which may have skin of any color. Accepted eye colors are black, brown, blue and hazel. However, horses with blue or partially blue eyes are accepted only if their registration certificate from a recognized breed association mentions the eye color; they are also accepted on horses of unknown pedigree if they are gelding or spaying.
