Primitive Markings in Non-dun Horses
Primitive markings can also occur on non-dun horses, even in breeds such as Thoroughbreds, Arabians, and Standardbreds, which are not known to have any dun individuals. The most common primitive marking found is a dorsal stripe; others do occur, but not without the dorsal stripe, even on non-duns.
Dorsal stripes and other primitive markings on non-dun horses are commonly called countershading dorsals because they seldom occur on clear-coated horses. The term countershading refers to any coloration that breaks up the outline of the animal: from a distance, countershaded animals - be they horses or birds - appear two-dimensional and are much more difficult to see. Primitive markings on non-duns are often seasonal, visible only when the horse is shedding its coat. Such primitive markings also seem to be heritable, as horses with prominent countershading dorsals often produce offspring with the same.

Famous quotes containing the words primitive and/or horses:
“Children can’t make their own rules and no child is happy without them. The great need of the young is for authority that protects them against the consequences of their own primitive passions and their lack of experience, that provides with guides for everyday behavior and that builds some solid ground they can stand on for the future.”
—Leontine Young (20th century)
“Kings and queens who wear a suit but once, though made by some tailor or dressmaker to their majesties, cannot know the comfort of wearing a suit that fits. They are no better than wooden horses to hang the clean clothes on.”
—Henry David Thoreau (1817–1862)
