What color is Benjamin Moore Smokestack Gray?

Benjamin Moore Smokestack Gray 2131-40 is a medium-depth blue-gray with a softly muted, slightly weathered cast. Its cool blue character is tempered by gray, keeping it grounded rather than bright or icy. In daylight, the color can read cleaner and a touch more blue, while lower or warmer lighting brings out its quieter gray side. Use it on bedroom or office walls for measured color without overwhelming the room, or on cabinetry for a restrained alternative to navy. Smokestack Gray pairs well with crisp white trim, pale oak, brushed nickel, charcoal, and warm off-white textiles.

What are Benjamin Moore Smokestack Gray undertones?

Smokestack Gray reads as a medium-depth, low-saturation gray with a subdued blue-green, or teal-leaning, cast in the supplied digital sample. The color feels cool overall, though the gray base keeps that blue-green bias restrained rather than bright. Benjamin Moore describes it as having touches of blue, green, and gray, which matches its visibly gray main family with a subtle cool blue-green direction. Warm artificial light may soften and slightly mute the cool cast, while cool daylight can make the blue-green lean more noticeable.

LRV of Smokestack Gray

Smokestack Gray has an LRV of 22.78% and refers to Medium colors that reflect a lot of 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 22.78%, 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.
