What color is Benjamin Moore Charcoal Slate?
Benjamin Moore Charcoal Slate HC-178 is a medium-dark gray with a restrained cool cast that can read slightly blue in clear daylight. Its muted saturation keeps it grounded rather than icy, giving walls a substantial, architectural look. In lower light, Charcoal Slate deepens toward a soft charcoal, while brighter rooms reveal its subtle blue-gray character. It suits a study, dining room, or bedroom feature wall, and can also give cabinetry a clean, tailored presence. Pair it with warm white trim, pale oak, brushed nickel, and natural linen to offset its cooler tone.

LRV of Charcoal Slate
Charcoal Slate has an LRV of 14.51% 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 14.51%, 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.
