What color is Behr Mountain Morn?
Behr Mountain Morn N400-1 is a light, muted gray-green with a soft, slightly cool cast. Its low saturation keeps the green understated, so it can read as a pale misty gray in cooler daylight and show more of its leafy undertone under warmer interior lighting. This shade is well suited to bedrooms, bathrooms, and quiet living areas where a clean but not stark wall color is wanted. Pair Mountain Morn with warm white trim, light oak, natural linen, and matte black or aged brass hardware for contrast. It can also give cabinetry or an exterior porch ceiling a subtle wash of color without looking overly green.

Warm light can make it look more olive and earthy, while cool daylight usually makes the green direction easier to notice.

LRV of Mountain Morn
Mountain Morn has an LRV of 68.8% 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 68.8%, 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.
