What color is Benjamin Moore Rainstorm?

Benjamin Moore Rainstorm CSP-50 is a muted mid-tone gray with a subtle green cast that keeps it from reading flat or bluish. Its low saturation gives walls a softly weathered, mineral-like appearance, especially in rooms with natural wood or stone. In bright daylight, Rainstorm can appear like a balanced gray-green, while lower light may bring out its deeper, earthier side. Use it on living room walls, a study, or painted cabinetry alongside warm white trim, oak, aged brass, and charcoal textiles. It also makes a grounded exterior option when paired with off-white siding or trim.

LRV of Rainstorm

Rainstorm has an LRV of 30.16% 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 30.16%, 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.
