Mineral Alloy vs Grey Blue
Mineral Alloy (Benjamin Moore) and Grey Blue (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 21-point LRV gap — 28 for Mineral Alloy vs 7 for Grey Blue — means Mineral Alloy will open up a space more effectively. A ΔE of 27.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
