What color is Benjamin Moore Grey?

Benjamin Moore Grey 2121-10 is a deep charcoal gray with a nearly neutral cast and a faint cool edge. Its low-light value gives walls a grounded, architectural look, especially in dining rooms, studies, or compact powder rooms. In bright daylight, Grey reads as a softened dark gray rather than black; under warmer evening lighting, it can appear a little richer and less stark. Use it on cabinetry, interior doors, or an accent wall with crisp white trim, pale stone, and light oak to bring out the contrast. Matte black hardware and brushed nickel both suit this shade’s clean, restrained character.

LRV of Grey

Grey has an LRV of 10.06% 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 10.06%, 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.
