Green Blue

RAL 5001 Green Blue is a deep teal-blue that captures the color of the open ocean on an overcast day. This versatile shade bridges the blue and green families, offering a natural, maritime quality that works well in coastal architectural projects, marine equipment, and industrial machinery. Green Blue has excellent UV stability in powder coating formulations, making it a reliable choice for exterior applications exposed to harsh weather and salt air environments.
