What color is Benjamin Moore Ambler Slate?
Benjamin Moore Ambler Slate CW-685 is a deep, low-saturation charcoal gray with a faint cool blue cast. Its near-neutral character keeps it grounded rather than overtly navy, while the dark value gives walls a defined, architectural presence. In bright daylight, the color can read as a clean slate gray; under warm lamps, it tends to look softer and more graphite-like. Use Ambler Slate on a study, dining room, powder room, or built-in cabinetry where a darker backdrop is welcome. Pair it with crisp off-white trim, pale oak, blackened metal, and muted stone finishes for a restrained, material-focused scheme.
LRV of Ambler Slate
Ambler Slate has an LRV of 11.78% 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 11.78%, 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.
