Mountain Mist vs Black grey
Mountain Mist (Benjamin Moore) and Black grey (RAL Classic) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 64-point LRV gap — 71 for Mountain Mist vs 6 for Black grey — means Mountain Mist will open up a space more effectively. A ΔE of 66.9 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Mountain Mist vs Black grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Mountain Mist on one side and Black grey on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
