What color is Behr Nocturne Blue?
Behr Nocturne Blue HDC-CL-28 is a deep, muted blue with a noticeable gray-green cast that keeps it from reading like a bright navy. Its low-light depth makes it especially effective in studies, dining rooms, or bedrooms where a darker wall color can create definition without looking black. In brighter daylight, the blue-green character becomes clearer, while evening lighting tends to bring out its charcoal-like restraint. Use Nocturne Blue on cabinetry or an accent wall with warm white trim, pale oak, aged brass, and natural linen to offset its cool, earthy depth.

LRV of Nocturne Blue
Nocturne Blue has an LRV of 6.7% and refers to Dark colors which means that this color almost does not reflect light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 6.7%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
