At one time, different universities had different practices concerning the color and style of the biretta itself. One author, nearly a century ago, reports that in his day the Roman universities gave a doctoral biretta in black silk, Louvain gave a biretta with a colored tuft according to the academic discipline in which the doctorate was awarded, and the Catholic University of America gave a velvet biretta with red tuft and trim to doctors of theology. The 'traditional' biretta at the Pontifical University of Saint Thomas Aquinas, "Angelicum", is white, to correspond to the white Dominican habit. Also, the academic senate of the "Angelicum" in its May 2011 meeting indicated that the black biretta may be used with trim and pom in the color of the particular faculty.
