Black and White are the official colors of Providence College. The colors come from the habit worn by the Dominican Order. On solemn and formal occasions, the white habit is covered by a long black cloak and hood which is called the cappa. It is the black cappa, which in ancient times was worn in the street, that caused the Dominicans in English-speaking countries to be called "Blackfriars."

The colors symbolize the ideals of the order. White typifies the Divine Truth preached by the Order and is indicative of the purity of life that must be characteristic of every Dominican. The black cappa is a constant reminder of the sacrifices that must be made in defense of the truth and the penance which is the means of preserving purity of life.
