A single dose dilution (one copy of Cr allele) results in palomino, buckskin or smoky black. The effect on black pigment might be very subtle. A double dose dilution (two copies of Cr allele) results in cremello, perlino or smoky cream. They are also called “double-dilutes” or “blue-eyed cream” and they share a number of characteristics. Their eyes are pale blue, paler than the unpigmented blue eyes associated with white colour or white markings, and the skin is rosy-pink.
