RAL 5022
Night Blue
RAL 5022 Night Blue is a deep indigo-blue that evokes the color of the sky just after sunset, when the first stars become visible. This dramatic, contemplative shade is specified for planetarium interiors, luxury cinema design, and architectural spaces where an immersive, nocturnal atmosphere is desired. Night Blue carries strong associations with mystery, the cosmos, and intellectual depth, making it a favored choice for observatory buildings, high-end bars, and exclusive lounge environments.
