Blanket is a white marking that expresses as a spotted patch of white on the horse's croup.
Blanket spots are randomly placed and vary in size, but in general should not be larger than the horse's hoof.
Blankets may be surrounded by patches of coat that are lightened (resembling Roan) or occasional spots darker than the base color (see examples below).
