Roan is a white pattern that leaves white hairs scattered throughout the coat. The amount of white varies seasonally, with the greatest expression in the spring when they start to shed and the least during the winter when it can at times be difficult to tell the horse is roan. Roan typically leaves the legs below the knee, mane, tail, and head solid colored. It also tends to leave a characteristic inverted V on the lower legs where the roan pattern stops and the solid legs begin. Roan is a simple dominant characteristic.
