Well, actually, if her sire is a buckskin, I would want to call her a palomino. With her sire being a buckskin, he's heterozygous for the cream gene, which means that he can pass the cream gene on to the foal, therefore making this mare a palomino. A buckskin is a bay with a creme gene added to dilute the brown coat to a golden color. So, if her sire is a buckskin, I would still want to know the color of her dam before I would say for sure that she's a palomino. After I've seen the pics that you took of her, I'm still going to say a very unusual shade of palomino that I've never seen before.
