A solid Paint is an American Paint Horse that does not display a pinto pattern.I have no idea, but the one's eye is exactly like our Mustang.
He's all white, but has those eyes. Is what you call a "solid paint" I think.
Where they are a solid color all around, but their skin is black and pink.
The second horse is a palomino. Do you have any pictures of the first where he isn't caked in mud?
