What color is Benjamin Moore Britannia Blue?
Benjamin Moore Britannia Blue 1623 is a muted blue-gray with a medium depth and a softly weathered cast. Its blue presence is restrained rather than bright, while the gray base keeps it grounded and adaptable across larger surfaces. In cooler daylight, Britannia Blue can read as a more pronounced slate blue; warm bulbs tend to draw out its softened gray character. Use it on a bedroom wall, built-in cabinetry, or an exterior door when a clear but low-saturation color is wanted. Pair it with crisp off-whites, charcoal accents, pale oak, brushed nickel, or natural linen for a clean, textured look.

What are Benjamin Moore Britannia Blue undertones?
Britannia Blue is a mid-depth, low-saturation blue-gray with a muted, slightly cool appearance. In the supplied digital color, the blue direction is most visible, with only a subtle green-leaning bias that is too slight to treat as a fixed undertone. Benjamin Moore describes it as a moody blue with a dark touch of gray, which matches its visibly softened blue character rather than a bright or clear blue. Warm artificial light may make the grayness feel more noticeable, while cool daylight can keep the blue cast more apparent.

LRV of Britannia Blue
Britannia Blue has an LRV of 18.06% and refers to Medium Dark which means that this color reflects very little light. Why LRV is important?
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 18.06%, 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.
