Coloring sometimes confused with dun (4)

I believe the answer is:

roan

(Other definitions for roan that I've seen before include "Horse with coat speckled with white or grey" , "nag" , "Reddish-coloured horse" , "(Horse) white-sprinkled coat" , "Horse with a coat of mixed colour" .)

I've seen this clue in The New York Times.
