RAL 250 40 35

Vivid Mandarin

RAL 250 40 35 Vivid Mandarin occupies hue 250, lightness 40, and chroma 35, a bold high-chroma orange that captures the electric intensity of mandarin peel and the vivid glow of molten amber. Designers choose it for safety signage elements, creative brand accent surfaces, and bold architectural feature walls. The strong chroma at moderate-dark lightness delivers a colour that is both appetizing and strikingly commanding in any built environment.
