RAL 120 70 25

Light Cerulean

RAL 120 70 25 Light Cerulean is defined by hue 120, lightness 70, and chroma 25, a warm luminous cyan that captures the fresh glow of cerulean skies reflected in still water. It is specified for bedroom feature walls, spa and wellness interiors, and decorative ceramic glazes where a calming aquatic freshness is desired. This cerulean tone works harmoniously with natural wood, linen textiles, and matte brass accents.
