Well, being satin, you know he's sa/sa, since satin is recessive. He's also spotted, so he's s/s, as that's also recessive. He's a lovely shade of orange, which in the US _probably_ means he's an undermarked brindle, Avy/*. Do you see any brown spotting, striping or smuding in his orange bits? They're quite firey and nice! There's a small chance he's recessive yellow, as that causes that coloring as well, but as common as the undermarked brindles are, it's your best bet. You could call him a satin pied undermarked brindle or simply satin pied fawn (pink-eyed red).
