My mare is due to foal any time, and the anticipation of what she's hiding in there is killing me! I don't know history on either her or the studs parents as far as coloration goes. My mare is a buckskin tobiano, and the stud is a spotted black. Well, he's not even really black, it's more of a deep charcoal color. He has fathered palominos, spotted, a sorrel (mare was sorel spotted) and just recently a foal that looks either champagne or a smoky cream maybe. Not sure because the mare is a devil and I can't get close to see in the stall.
