Stairway up to the San Carlos Street overpass, as seen from the tracks, just south of Diridon station in San Jose. Color fringes like those on the edges of steps in photos like this one are not that unusual, generally due to a chromatic artifact that digital image sensors are prone to; however, in this case they are actually graffiti on the steps seen edge on!

Shot with the Nikon D70s and the 18-70mm f/3.5-4.5 zoom at 18mm, ISO 400, f/9, shutter 1/500 sec. Noise removal in Photoshop CS4.
