What color is Sherwin Williams Mercurial?

Sherwin Williams Mercurial SW 9550 is a light, muted neutral with a soft gray-beige cast and a gentle warmth from its slightly rosy-tan undertone. Its low saturation keeps it quiet on broad walls, where it reads as a pale greige rather than a distinct beige or gray. In bright daylight, Mercurial can look clean and lightly warmed, while lower or cooler light may bring out more of its gray side. It suits bedrooms, living rooms, and open-plan interiors where a subtle background color is needed without the starkness of white. Pair it with creamy trim, weathered oak, linen upholstery, charcoal accents, or matte black hardware for contrast.

LRV of Mercurial

Mercurial has an LRV of 61.03% and refers to Light colors that reflect most of the incident 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 61.03%, 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.
