What color is Behr Flannel Gray?
Behr Flannel Gray N520-3 is a light-to-medium gray with an unusually even, softly muted cast. Its near-neutral color balance keeps it from reading strongly blue or brown, though the faint warmth in the shade can become more noticeable beside crisp white trim. In bright daylight, Flannel Gray appears clean and understated; under warm lamps, it may lean slightly softer and greige. It is a practical wall color for living rooms, bedrooms, hallways, or open-plan spaces where a low-contrast neutral is wanted. Pair it with warm white, charcoal, natural oak, brushed nickel, or black accents for a grounded, uncluttered look.

LRV of Flannel Gray
Flannel Gray has an LRV of 42% and refers to Light Medium colors that reflect half of the incident 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 42%, 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.
