What color is Behr Atmospheric?
Behr Atmospheric PPU12-15 is a muted, medium-depth blue-gray with a lightly softened green cast. Its cool character is noticeable without feeling icy, thanks to the color’s gray base and restrained saturation. In daylight, it can read as a calm blue-gray, while warmer artificial light may bring its subtle green undertone closer to the surface. Atmospheric is well suited to bedrooms, bathrooms, and home offices, as well as painted cabinetry where a quiet contrast is wanted. Pair it with warm white trim, pale oak, brushed nickel, charcoal accents, or soft clay-colored textiles for a grounded palette.

LRV of Atmospheric
Atmospheric has an LRV of 29.02% and refers to Medium colors that reflect a lot of 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 29.02%, 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.
