He could just be a pinto horse...its not just a colour I have a pinto/connemara :P
Judging by the first pic it looks like he has a bit of andalusian in him cos of his body shape...
But.....he does kinda have the same conformation as my mare but he's not a paint :P
He could very well be a paint, but you'd have to be certain of his breeding to be sure. The only difference between paint & pinto is the breed (paints can ONLY be of TB or QH breeding, whereas a pinto is any another breed with these markings).
I agree with annaleah in that he could have saddlebred in him, of maybe TWH.
He is a Tobiano Pinto though ;)
My guess, by the size of his head and the slope in his shoulder...Spotted Saddle horse which is a generalized breed registry for anything gaited with color. Here is a friends Spotted Saddle for comparison
