The cremello is a characteristic appearance in horses due to the presence of cream gene, producing several coat colors. Its action on a chestnut base color creates the palomino while on a bay base produces the perlino or buckskin. The general effect of the cream gene is to lighten the eye, skin, and coat.
When one copy of the gene occurs, it acts as a dilution gene lightening red to gold or yellow, especially on the mane and tail. When two copies occur, black hairs turn reddish while red hairs become cream. A single copy has a minimal effect on the eye color, but two copies make the eyes blue and the skin turns rosy pink.
If a horse has one copy of the cream gene, color dilutions like palomino, buckskin, and smoky black occur while two copies produce cremello, perlino, and smoky cream. Cremello horses are characterized by a cream body with white or cream mane and tail. These horses are registered by the Cremello and Perlino Educational Association (CPEA) and American White & American Crème Horse Registry.
