What color is Behr Prairie Sky?
Behr Prairie Sky S510-1 is a light blue-gray with a cool, softly muted appearance. Its gentle gray cast keeps the blue from reading overly sweet, making it a practical option for bedrooms, bathrooms, or an airy home office. In bright daylight, the color can look cleaner and more powdery blue, while lower or warmer light may bring its gray side forward. Pair Prairie Sky with crisp white trim, pale oak, brushed nickel, or charcoal accents for a restrained contrast. It is especially well suited to full walls, where its low saturation gives a room color without making the space feel heavy.

LRV of Prairie Sky
Prairie Sky has an LRV of 64.99% and refers to Light colors that reflect most 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 64.99%, 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.
