What color is Benjamin Moore Sierra Spruce?

Benjamin Moore Sierra Spruce 2108-20 is a deep, muted brown with a noticeable warm cast and a softly weathered appearance. Its low-saturation finish keeps the color grounded rather than reddish, making it feel substantial on walls without looking overly dramatic. In brighter daylight, Sierra Spruce shows more of its earthy brown character; at night or in shadow, it settles into a darker, nearly blackened brown. It suits studies, dining rooms, and entryways, especially when paired with creamy off-whites, aged brass, natural oak, or textured linen. On cabinetry or a single accent wall, this shade adds depth while allowing lighter trim and pale stone surfaces to stand out.

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 9.69%, 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.
