It's a Tobiano trait. I call it roaning, but that's not what it is. My buckskin paint has it on his neck and it's grey like that as well. His just seems to be loudly expressed. Cute boy! Posted via Mobile Device
Interesting, I have seen the tobiano roaning/blurring you are talking about before, but never like this... I guess its grey appearance threw me off, and that it splits his "colored" portion in half there.
