I would guess his sire is a brownskin, if he's for sure got cream.
Equiniphile and Super Nova, I agree with NdAppy: Your horses are brown.
Peppy, he's bay. There's nothing special about that. He isn't a "mahogany bay" or a "blood bay." He's bay. The most interesting thing about that is that he may have pangare, which isn't determinable right now because he's so young.
Sorry for being short, but I'm really not sure why people keep asking if their horse is a specific shade as if it's going to make it uber speshul or something.
