What color is Benjamin Moore Blue Note?
Benjamin Moore Blue Note 2129-30 is a deep, muted blue-gray with a noticeably cool cast and a charcoal-like weight. Its restrained saturation keeps it from reading as bright navy, giving walls a grounded, shadowy look instead. In strong daylight, the blue-gray character is clearer; under warm lamps or in dim rooms, it can appear closer to softened charcoal. Use it for a dining room, library, powder room, or built-in cabinetry where a dark color can add definition without feeling overly stark. Pair Blue Note with warm white trim, pale oak, brushed brass, natural linen, or light gray stone to bring out its quiet blue presence.

What are Benjamin Moore Blue Note undertones?
Blue Note is a deep, low-saturation navy that reads as blue first, with a muted, near-charcoal cast. In the supplied digital sample, its blue direction is clear, while any green-leaning bias is subtle and not strong enough to define the color. Benjamin Moore describes it as a deep navy with dark gray undertones, which helps explain why the blue appears restrained rather than bright or vivid. Warm artificial light may bring out its grayed, slightly softened character, while cool daylight can make its blue direction look more apparent.

LRV of Blue Note
Blue Note has an LRV of 9.02% and refers to Dark colors which means that this color almost does not reflect 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 9.02%, 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.
