The lighting in an area leading up to Blackfriars Bridge in London was revamped by lighting designers Firefly using Crescent CLVS linear colour changing RGB system.

Seventeen lengths of the slim profile were installed behind curved mirrors above a pedestrian ramp area on the north bank entrance to the bridge, to shine up into the bridge structure.

The lighting system was programmed by Crescent with strict instructions for no red, blue or green alone to be used, but subtle mixtures of the three colours.
