You can, however, see a distinct dorsal. Poseidon was referring to the OP's horse when she said there was no dun factor.
I'd disagree that the horse I posted has a clear dorsal. I'd say it's actually quite fuzzy and light colored, not at all the "drawn on with a marker" look that most duns exhibit. If you go to the link in his name, you can see that he has no leg or shoulder barring, either (and he has enough color on both of those areas that it would show up if it were going to).
I'm not saying that the OP's horse is definitely a dun palomino (clearly he has the sooty gene... I don't think anyone's debating that one). I'm just saying that it's not outside the realm of possibilities and that if she really wanted to know, she'd have to do genetic testing.
