I think he is a smokey blck pinto too.. He gets the dilute gene from his sire, and his mom is black.. It kind of all fits into place! He is adorable by the way!
He is clearly a black pinto. No doubt about that as that is the typical mousy black color of a new born foal. But, he could have inherited the cream gene as he has a 50% chance of that happening. If he did, then he would be a smokey black pinto. The only way to know for sure is to get him tested, or to wait until he sires a foal that is a dilute out of a non-dilute mare, or he sires a double dilute.
