What color is Benjamin Moore Powell Gray?

Benjamin Moore Powell Gray CW-665 is a muted, medium-dark blue-gray with a cool, slate-like cast. Its restrained saturation keeps it from reading overly blue, giving walls a grounded, architectural look rather than a bright coastal feel. In daylight, the blue-gray character is most noticeable, while lower or warmer lighting can make the shade appear deeper and more charcoal-leaning. Powell Gray is well suited to studies, dining rooms, mudrooms, or exterior trim where a substantial color is wanted without using black. Pair it with soft white paint, pale oak, aged brass, charcoal textiles, or natural stone for a clean, layered finish.

LRV of Powell Gray

Powell Gray has an LRV of 14.61% 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 14.61%, 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.
