RAL 4005
Blue Lilac
RAL 4005 Blue Lilac is a soft, cool-toned lavender-violet that bridges the blue and violet families in the RAL system. This calming, contemplative shade is widely used in educational buildings, healthcare interiors, and modern office environments where a serene atmosphere supports concentration and wellbeing. Blue Lilac has roots in the Art Nouveau movement, where muted violet tones were favored for their meditative quality. It pairs effectively with pale greens and warm greys in balanced interior schemes.
