There are some, mostly minor, differences in the designs of cappelli, depending on the rank of the wearer. The pope wears a red cappello with gold cords . Cardinals formerly also had the privilege of wearing a red cappello, but this rule was overturned by Paul VI, and now Cardinals' cappelli are black, as are those of all other clerics. A cardinal may have a cappello with red and gold cords with scarlet lining. A bishop's may have green and gold cords with violet lining. A priest may substitute black lining for his. Cappelli for deacons and seminarians have no distinguishing items.
