What color horse will you get if you breed a blue roan to a palomino?

You have several different possibilities, depending on the genetic makeup of the two horses. Some of the factors that are not apparent are whether the roan is homozygous for roan (he carries two genes for it), whether he is homozygous for black, and whether the palomino carries the gene for bay, either in one or two copies.

Some of the possibilities are: Palomino, buckskin, smokey black, sorrel, bay, black, red roan, blue road, bay roan, or a palomino or buckskin with roaning.

If the roan has two genes for roan, you will get a roan no matter what. If it has two genes for black, you will NOT get a palomino, sorrel or red roan. Otherwise, there is a 50% chance of getting any roan.

In general, there is a 50% chance of getting something with the dilute (palomino) gene. These include palominos, buckskins, and smokey blacks.
