What color is Behr Blue Fir?

Behr Blue Fir S430-7 is a deep, muted green with a noticeable gray cast that keeps it grounded rather than overly forest-like. Its blue-green undertone gives the color a cool, shaded character, especially in north-facing rooms or low evening light. In brighter daylight, Blue Fir reads a little clearer and more balanced, while warm artificial lighting can bring forward its softened green side. It has enough depth for kitchen cabinetry, a dining room, or a dramatic study wall without appearing black. Pair it with warm white trim, pale oak, aged brass, charcoal textiles, or creamy stone for contrast that does not compete with its quiet complexity.

LRV of Blue Fir

Blue Fir has an LRV of 11.31% and refers to Medium Dark which means that this color reflects very little light. Why LRV is important?

Light Reflectance Value scale illustration

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 11.31%, 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.
