Cremello is a color of horse consisting of a cream-colored body with a cream mane and tail. It is the result of double dilution on a red base coat. The horse has pink skin, blue eyes, and fades from a light cream when born to almost white as an adult.
Cremello horses are not albino: the eyes are blue, whereas a true albino would have red eyes. They are also not true white horses, which have brown eyes and no dilution factor.
For more information on cream coloring and the dilution gene see creme gene. For more information on true white horses, see Gray (horse).
A cremello is homozygous (2 copies) for the dominant cream gene on a chestnut base -- perlinos (bay base) and smoky creams (fl base) are also homozygous but the base color is different and may affect resulting foal colors.
A cremello foal usually occurs between palomino x palomino, palomino x buckskin, palomino x smoky fl, cremello x cremello/perlino or smoky x smoky matings; but can also occur when breeding greys, fls and other colors where the cream gene is not visually apparent.
A cremello foal is born with light blue eyes and pink skin and it keeps those two items for the remainder of its life.
