What is the Colortest Dun?

The Dun coat color is considered as the the “wild-type stateand we can found it in wild equine like Przewalski horses, zebras etc.

The black dorsal stripe is the more visible Dun marking, however we can also observed to a lesser degree leg barring, shoulder stripes and concentric marks on the forehead.
