What color is Behr Boreal?
Behr Boreal N420-5 is a muted mid-tone green-gray with a grounded, slightly cool cast. Its softened saturation keeps it from reading like a sharp botanical green, giving walls a quiet, natural-looking depth instead. In bright daylight, Boreal can appear more balanced and gray-green, while lower or warmer light may bring out its earthy olive side. It suits bedrooms, offices, mudrooms, and exterior siding where a substantial color is wanted without a dark finish. Pair it with warm white trim, charcoal accents, weathered wood, matte black hardware, or stone in gray and taupe tones.

What are Behr Boreal undertones?
Boreal is a midtone, very muted mossy gray-green. The HEX sample has a subtle green bias, but its low chroma turns that hue into a neutral-looking color rather than a clear green. Warm light can make it look more olive and earthy, while cool daylight usually makes the green direction easier to notice.

LRV of Boreal
Boreal has an LRV of 19.24% and refers to Medium Dark which means that this color reflects very little 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 19.24%, 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.
