Nocturne Blue

HDC-CL-28

Nocturne Blue by Behr is a dark, muted blue with cool gray undertones and a slight green-blue lean. Its LRV of 28.4 means it absorbs considerably more light than it reflects, giving it a deep quality suited to accent walls or cabinetry in well-lit rooms. The gray influence keeps the blue from reading too saturated.

It coordinates with Behr Creamy Mushroom and Swiss Coffee as warm neutral counterpoints, while Ultra Pure White provides clean trim contrast. Behr Classic Silver or Midnight Blue maintain a cohesive cool-toned palette alongside it.

LRV measures how much light a color reflects, from 0 (black) to 100 (pure white). Below about 50 a color needs good lighting to avoid going flat, 60 and up helps brighten a room, and most whites sit above 80.
