yup, but it's called counter shading :) It can be barely there to very prominent. I've got a picture of a buckskin with a very inky black one somewhere. My haflinger has a faint one going down her back as well...hard to pick up with a camera, but visible to a person standing there.

here is a fun page that shows some horses with counter shading that mimics dorsal stripes Dun Central Station - Look-A-Like Colors

may i ask how one tells the difference between a dorsal stripe and countershading? sometimes i just dont know :(

Countershading tends to have blurred edges, whereas a true dorsal stripe will look like it was drawn on with a large marker.

Sort of. More like a vestigial coloring than anything else. Most animals are darker from above and lighter from below, or evolved from animals that were. The source of that pattern is from simple natural selection which favored sea creatures/animals being camoflaged by the sky when seen from below and land creatures/animals being camoflaged by the ground when seen from above...

Dorsal stripe or counter shading?

here are two pics of the buckskin I was talking about with the dark counter shading. Took this at our local parade we have, I'm in charge of lining up the horses. The group is SOLA (Southern Ohio Ladies Aside).

Idlepastures--do you have a pic of that without so much sunglare? I'm inclined to think dun just by looking at the base of the tail, but so much of it's washed out there I can't really see.
