What do you plan to do with him?
There is no part bred paint registry and chaps can be funny about part pedigree American breeds.
I don't think he is grullo, bay dun maybe? What is the dam's breeding?
If you want a paint there are better choices on the same site. If you just like the look of him then go and see.
What I meant was Chaps can be funny about grading part pedigree American breeds as I found out with my paint mare ( past owner died and papers mixed up/ lost so we don't know which went with which & too old to use DNA.)
Not a problem for a gelding.
He doesn't look like the grullo foals I am used to.
SamanthaG are you the seller?
He doesn't look grullo to me either, I would have said yellow dun, if he definitely has dun, otherwise buckskin or even possibly a very pale bay.
took me a while to notice the other foal fast asleep on the floor!
