After WXXW (channel 20, allocation later occupied by PBS member station WYCC)—the second-to-last television station in the market that continued to broadcast in black-and-white—went dark in 1974, channel 26 remained the only television station in Chicago that still broadcast its programming in monochrome. Just prior to the Christmas season of 1974, the station installed and tested color transmission equipment, which broadcast on a low-power relay station located in Lincoln Park. In November 1974, the color and black-and-white signals traded transmitter facilities for the remainder of the holiday season; on December 31, 1974, the translator was taken offline as channel 26 started to broadcast in color full-time.
