Okay Bob, I get your joke - a “painted” pony. It does look like a painting where the paint ran.
But there is a difference between the appaloosa and the pinto horses. The appaloosa horse has spotted and/or “spattered” coloring whereas the pinto has a dark background with random patches of white. The dark background is brown. The Native Americans preferred the pintos because of their natural camouflage. The two are indeed different breeds. As with anything else - like cats and dogs - breeders have been busy coming up with different color variations by selective breeding - in both breeds. Can’t just leave nature alone, can they?
