Transparent Texture

Dun Factor

Dorsal Stripe

A wide, definite stripe running the full length of the back from the shoulder bar through the tail. Most desirable is one with barring off the dorsal stripe running towards the stomach.

A small dorsal or broken dorsal stripe is not a desirable point. Some horses will carry a partial or full dorsal from the chest to the rear of the horse on the underline.​

Face Masking

Definite, contrasting masking preferred. Cob webbing is of many types but should show definite lines and contrast. Ear tips should show contrast to body coast and framing and horizontal barring on the backs of the ears is desirable.

Leg Barring & Mottling

Horizontal striping on the legs evaluated on the amount of striping and contrast. Diversified blotching may be in conjunctions with barring or alone. Score on contrast and extent.

Mottlings may show on the neck, from the tip of the dorsal down the leg, to the barring on the front legs. The hind legs may be mottled from the hips down to the barring.

Shoulder Stripe & Rib Barring

Definite contrasting striping over the withers and along the rib lines is preferred to cape markings or body coast shadowing.


A Dun horse is most easily distinguished by his primitive or dun factor markings.  These markings are darker than the body color, and most often the same color as the mane and tail. 


One body color is not preferred over another. Scoring is based on the contrast of body color and dun factor markings.
