The Macchiato (M) coat color was documented in a single Franches-Montagnes stallion. He displayed a dilute coat color, blue eyes, extended face and leg markings, and white on the body.

Pattern-1 (PATN1) is a major effect modifier of Leopard Complex Spotting (LP). While the LP variant itself does not produce much white spotting, the PATN1 variant is associated with white markings over half of the body at birth.

Pearl (prl) is a dilution. A single prl allele does not affect the coat color, though may cause some skin lightening/freckling. Horses with two prl alleles are visually similar to horses with the champagne dilution, including skin and eye color.

Sabino 1 (SB1) is characterized by extended white markings on the legs and face, often accompanied by a belly spot and roaning throughout the coat. Homozygous horses (SB1/SB1) are born nearly to completely white. Unlike other white patterns, Sabino horses usually have dark colored eyes.

Silver (Z) is a dilution that only affects black pigmentation. Horses often have a lighter mane and tail. Silver foals are born with striped hooves and white eyelashes. Bay silver horses retain the normal reddish body color combined with diluted legs, which is often misidentified as a chestnut.

Splashed Whites are white spotting patterns characterized by large white markings on the legs, face, and sometimes the tail/belly, giving a horse the appearance of being dipped in paint. Often, splashed white horses have blue or partially blue eyes, and may be deaf. On rare occasions, splashed white may be hidden.

Splashed White 1 (SW1) is found in many breeds and presents as normal markings in a heterozygous horse and typical splashed white markings in a homozygous horse.

Splashed White 2 (SW2) is found in Quarter Horses and can present as "normal" to "typical splashed white" markings.
