What's a buckskin? A Cr gene and a black gene with a agouti gene?
He could be a dark bay, black (which I doubt), or a smokey black. I'm leaning towards dark bay, as the bleaching on his body very obviously stops at the legs and it seems very uniform.
Here's my DNA tested smokey black colt:
You can also see the white/blonde hairs in his tail, which he still has at three years old ;)
Interesting because Bourbon looks alot like him her mama was a tested smokey black and daddy was a bay roan my filly has the same light markings and she was also born a silvery color I think I need to have her tested.
