DNA will not tell you what color a horse is. By his mousey brown color I'm pretty sure he does carry 1 creme gene. So I would agree with Smokey silver black.
Lutes' Komo Dandy is an amazing driving stallion. He lived just a few miles from me, and is now near Lansing, MI. Chestnut pinto. The VVF mare is a silver dapple. If you go to Cavanaugh's West Wind Farm you will find photos of Dandy.
