The platform walls on both levels have no trim line, but there are mosaic name tablets reading "50TH ST." in white sans-serif lettering on an Ultra Violet background with black border. Small tile captions reading "50" in white lettering on black run in regular intervals between the name tablets, and are also present on the lower level's curtain wall. Blueberry I-beam columns run along all the platforms at regular intervals, alternating ones having the standard black station name plate with white lettering.
