In the early years of the university, the school colors were black and gold. Tradition holds that in the 1890s, a faculty member suggested the school adopt colors more representative of New Mexico. Crimson and silver were initially suggested based on, respectively, the crimson evening glow of the Sandia Mountains and the description of the Rio Grande as a silver ribbon winding through the valley as seen by students and professors taking picnics in the Sandias. Crimson was later changed to the cherry color which is the color of the Sandia sunset. Cherry and Silver became the official colors in 1897. The school also used turquoise as an official color from 1973 to 1979.
