University of Rhode Island has UNC’s colors and the tune from UNC’s fight song, with different lyrics.
Georgetown’s colors are blue and gray because when the Civil War broke out, students and alumni ended up on both sides of the conflict.
Providence College has black and white because the Dominican Friars who run the school wear black and white robes. They are sometimes called the ‘blackfriars’ to distinguish them from the ‘brownfriars’ (Franciscans).
