I’ve been photographing blue and white lines in local parking lots (in the US) under different conditions. Some of them are in pristine condition (Brand New Paint Job), some are in a state of demise (Derelict Parking Lot), I’ve zoomed in on some to show the effect of weather on the outdoor paint (Parking Lot Impasto).
The blue line below was painted on a the curb adjoining the parking space upon which the white line was painted.
