How Charcoal Slate behaves on a wall
Benjamin Moore publishes a light reflectance value of 40.2 for this shade. At LRV 40.2 this sits mid-scale — dark enough to hold its own against white trim, light enough not to close a room in. Mid-tones shift the most between daylight and lamplight, so check it at both ends of the day. For trim that reads as a clear edge rather than a smudge, aim about 30 LRV points away in either direction — under LRV 10 or over LRV 70. Its red and blue channels are within a few points of each other, so it has no undertone worth naming — it takes its cast from whatever it sits beside. Order by the code, not the name, and put a test patch on the wall before you commit — a screen cannot show you how this shade behaves in your own light.

The closest color to Benjamin Moore Charcoal Slate from each brand we carry, measured with CIEDE2000 on the manufacturers' published color values. Below 1 the difference is practically invisible; below 2 you'd only notice it with the chips side by side. Screens and printed chips aren't paint, so compare real samples before you buy. In the Muro app you can put two of them on a photo of your own wall and look at them in your light.
