Cream: Unlike agouti, which can only act on the black gene, cream can modify any color it acts in conjunction with, though it is most commonly seen combined with chestnut, bay, and black. The cream gene is an incomplete dominant, meaning it is always expressed when it's present, but it acts differently in its heterozygous (1 copy of the gene) and homozygous (2 copies of the gene) states. Simply put, horses with one copy of the cream gene will have a diluted coat; horses with 2 copies will have a doubly diluted coat. Double dilutes always have blue eyes. The cream gene does not effect black hairs in it's single form (nCr), only in it's double form (CrCr).
Palomino: Chestnut + 1 Cream gene
Chestnuts have no black hairs, so the entire coat is diluted. The mane and tail are almost always white. There are several different shades of palomino like the isabella palomino.
Chocolate palomino
Palomino with sooty
If you look closely, you can see the original coloring around his throat and around his flank.
Isabella palomino
Cremello: Chestnut + 2 Cream genes
Cremello is basically a very pale palomino color---white markings are still discernable against the pale cream colored coat. Cremellos have blue eyes and light colored skin. (The only true pink skin is under white markings.)
Buckskin: Bay + 1 Cream gene
Because the cream gene doesn't affect black hairs, the dark points remain even after the bay body color has been diluted. There are several different shades of buckskin such as the buttermilk buckskin.
Buttermilk buckskin
Perlino: Bay + 2 Cream genes
When two cream genes are present, the body color becomes very pale, and the black points are diluted to a red or brown color.
Smoky Black: Black + 1 Cream gene
The cream gene has very little affect on black hairs in its single state, so smoky black is very hard to distinguish from brown or (very sooty) dark bays. Often the best way to tell if the horse carries the cream gene is to have it genetically tested.
Another smokey black
Smoky Cream: Black + 2 Cream genes
This Akhal Teke is thought to be a smoky cream. Notice how his points are still a darker shade than the rest of the body.
