I saw several Crioulo horses in Brazil with an interesting color combination of pangare on a palomino dun coat. The palomino dun looks a bit like plain palomino at first glance, but the brown dorsal stripe is visible on the back and tail, and there are some leg stripes. The pangare marking gives the horse a bit of white around the muzzle, armpits, belly and flanks. These horses are in winter coats.
The roached mane is typical of the gaucho region of southern Brazil. On the bay horse in the first picture you can see more clearly that a "handle" is always left long at the withers, to aid the rider in mounting. The horse in the background is the color called grulla.
