What color is Behr Liquid Mercury?
Behr Liquid Mercury N510-5 is a medium blue-gray with a noticeably cool, softened cast rather than a stark industrial look. Its muted saturation keeps it grounded, making it a useful wall color for bedrooms, home offices, or bathrooms that need more presence than pale gray. In north-facing rooms, Liquid Mercury can read crisper and slightly bluer, while warmer afternoon light brings out its quieter charcoal-gray side. Pair it with clean white trim, pale oak, brushed nickel, and charcoal accents for a restrained, layered palette. It also has enough depth for cabinetry or an exterior front door when balanced with lighter surrounding finishes.

LRV of Liquid Mercury
Liquid Mercury has an LRV of 19.35% 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 19.35%, 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.
