Dun

Dun Colors are usually a sandy/yellow to reddish/brown coat.
Their legs are usually darker than their body and sometimes have faint
"zebra" stripes on them.
Dun Horses always have a Dorsal Stripe running down the
middle of their back. Some even have a dorsal stripe that continues down the
horse's dock and tail, and through the mane. The dun color makes the horse's
nose and sometimes the rest of the face a darker color than the body which
is called "Face Masking".
The different Dun colors include a Bay Dun and a Red Dun. Bay Duns have a
bay color, but they are not bay since they have the dun characteristic of
the dorsal stripe down the middle of their back. An uneducated horse-person
might think this is a buckskin or even a bay.
The Red dun horse has reddish/chestnut highlights with a dorsal stripe down
the back, and the legs a darker color than the body.
