Red roan horses are roan horses that have a chestnut or sorrel (which is reddish brown in color) base coat. The base coat is intermixed with white hairs throughout the coat making the horse a light reddish color. Sometimes red roan horses are called strawberry roans if they appear especially reddish in color. In addition to red roans, there are also blue roans, bay roans, buckskin roans, palomino roans and even black roan horses.
