In April 1985, the CU athletic teams were given the option of blue or black. The football team chose to wear black, and at Folsom Field the background for the signature "Colorado" arc (at the base of the seats behind the south end zone), blue for four years, was repainted black as well. On the football uniforms, the blue was reduced to a stripe on the sleeve for three seasons (1985–87) before being dropped completely in 1988. In 2007, CU debuted new football jerseys that reintegrated silver as a uniform color.CU Unveils New Football Uniforms - CUBuffs.com—Official Athletics Web site of the University of Colorado
