As of May 17, riders of Denver’s year-old light rail get a colorful surprise at the Federal Center Station stop in Lakewood. In Color Field, artist Ivan Toth Depeña—who has an architecture degree from Harvard—has installed 18 permanent steel structures supporting rectangular glass lenses of varying colors along the station’s ramps, stairs and walkways. The resulting array of colorful shadows, which change as the sun moves through the sky and cover every surface in sight, is meant to be kaleidoscopic. Second Pl. and Routt St.; rtd-fastracks.com.
