High Quality Content by WIKIPEDIA articles! Seal brown is a hair coat color of horses characterized by a near-black body color, with a black mane, tail and legs, and reddish or tan areas around the eyes, muzzle, behind the elbow and in front of the stifle. The genetically and visually similar dark bay coat color, which also features black points and a near-black body, differs from true seal brown in the absence of these true tan markings. The liver chestnut coat is all-over reddish brown, and is sometimes confused with seal brown; true seal browns have black points, while liver chestnuts do not. Several theories have been advanced in the last century to explain the heredity of the seal brown coat. Today, true seal brown horses can be distinguished from bays by a DNA test.
