champagne: Classic and sable champagnes are difficult to distinguish without a DNA test. Grullos and classic champagnes are both dilutions of the black coat, and typically have black or dark points and dove-gray coats. However, Grullos, in absence of any other dilution factors, are not born with pink skin and blue eyes, while champagnes always have these traits. As adults, grullos will retain their dark brown eyes and black skin, while champagnes have pinkish freckled skin and hazel eyes. Grullos, like all duns, will possess primitive markings, and their coats are typically a cooler, slate shade, while classic and sable champagnes are chocolate-toned. The points and primitive markings on the grullo are black, while the points on classic and sable champagnes are brown. Grullos will have dun ancestry and champagnes will have champagne ancestry. Red dun vs. Dark gold champagne: Some gold champagnes have darker bodies and self-colored manes and tails. These horses may resemble red duns, however red duns have distinct primitive markings and do not possess pinkish freckled skin or hazel eyes as adults, nor the bright pink skin and bright blue eyes of champagne foals. Blue-eyed cream vs. Champagne: Blue-eyed cream is a collective term for any horse homozygous for the Cream gene (cremello, perlino, etc.). Blue-eyed creams, as their name suggests, have blue eyes from birth through adulthood and also have pink skin. Typically their blue eyes are quite pale, and are easy to distinguish from the sky blue eyes of champagne foals and the hazel eyes of adult champagnes. Their skin may have a scant few black flecks, but the abundant freckles of champagne skin are absent. The respective shades of pink skin and blue eyes are slightly different. Leopard vs. Champagne: The Leopard complex is responsible for the spotted coat of the Appaloosa and other breeds. Even when a spotted hair coat is absent, other traits produced include mottled skin and a white sclera around the eye but generally the eye itself is dark brown. These mottles are alternations between unpigmented pink skin and pigmented skin, which is usually black (thus the mottles are black on a pink background). The mottles are substantially larger than the freckles of champagne skin, and leopard complex horses do not necessarily have light eyes. Pearl vs. Champagne: In the homozygous state, or when combined with cream, the Pearl gene produces a diluted apricot to buff color, pale eyes
