ok so I have a 3 1/2 coming on 4 paint tabiano horse. She is bay and white but she has this area on her neck where the bay goes to black not dark bay but black. The area has white splotches on black. Her body is bay, her main and tail is black,and dark brown, with a few strands of white here and there. So my question is does this make her a "tri- color" paint?
