RAL 2002
Blood Orange
RAL 2002 Blood Orange is a vivid, intense red-orange that commands immediate attention. This is the signature color of the U2 line on the Berlin U-Bahn, where it helps passengers quickly identify their route. Blood Orange carries urgency and energy, making it effective for emergency equipment, fire safety installations, and bold commercial branding. Its high saturation ensures visibility even at a distance or in low-light conditions.
