RAL 1023
Traffic Yellow
RAL 1023 Traffic Yellow is a standardized road safety yellow designed for maximum visibility in transportation contexts. This color is used on the U4 line of the Berlin U-Bahn and the S6 line of the Milan S Lines, among many other public transport systems. Traffic Yellow meets stringent visibility requirements for road signage, lane markings, and pedestrian safety infrastructure. In powder coating, it is specified for bollards, crash barriers, and traffic management equipment that must remain visible in all weather conditions.
