What color is Farrow and Ball Blue Gray?

Farrow and Ball Blue Gray 91 is a light, muted gray with a noticeable green-beige cast that keeps it from reading as a cold neutral. Its low saturation gives walls a soft, chalky appearance, while the slightly earthy undertone becomes more apparent in daylight. In cooler rooms, Blue Gray can look like a pale mineral gray; under warmer lamps, it shifts toward a gentle khaki-gray. It suits bedrooms, studies, and quiet living spaces, especially alongside off-white trim, natural oak, linen, aged brass, and olive-toned textiles.

What are Farrow and Ball Blue Gray undertones?

The supplied digital sample reads as a mid-light, very muted gray with a subtle yellow-green lean rather than a strongly blue appearance. Its undertone appears to be a slight yellow-green bias relative to the gray base, though that bias is subtle and may not represent the paint formula itself. Farrow & Ball describes Blue Gray as a “cool blue grey,” which identifies blue-gray as the intended main color family, even if this particular digital sample looks more neutral-to-warm. Warm artificial light may bring out its faint yellow cast, while cool daylight may make the gray aspect look clearer.

LRV of Blue Gray

Blue Gray has an LRV of 44.62% and refers to Light Medium colors that reflect half 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 44.62%, 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.
