Dun
You recognise a dun by the dorsal stripe along the back and the primitive markings.

What does this colour look like?
A diluted body (yellowish-brown, reddish or greyish) with a clear dark dorsal stripe along the back, often zebra bars on the legs and shoulder stripes. Head and lower legs stay darker.

More about the genetics
Dun is dominant (D). It dilutes both red and black body pigment and leaves head, lower legs, mane and tail undiluted, with the primitive markings as its signature. The two recessive non-dun alleles differ: nd1 horses are not dun-diluted but may show faint primitive marks; nd2/nd2 horses have neither dilution nor primitive marks.
