We will be happy to help you identify your horses color by researching its genetic history. First you will need to provide us with a pedigree at least three generations worth, and multiple full body color photos of your horse. Color photos of the parents as well will be extremely helpful since most unusual colors are not properly recorded by the majority of registries.
The two best ways to verify a horses color is thru genetic testing which in most cases is available thru UC Davis. If testing is not available a color record of foals produced can also be a great way to distinguish any hidden genes your horse may be carrying.
We have an extensive reference on horse colors and their factors available in our Color reference pages.
