The biretta may be used by all ranks of the Latin clergy cardinals and other bishops to priests, deacons, and even seminarians (who are not clergy, since they are not ordained). Those worn by cardinals are scarlet red and made of silk. After the Second Vatican Council the ceremony of giving the galero to cardinals was replaced with giving the biretta. The biretta of a bishop is amaranth in color, while those worn by priests, deacons, and seminarians are black. The pope does not make use of the biretta.
