Quarry Rock vs Cement grey
Quarry Rock (Benjamin Moore) and Cement grey (RAL Classic) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 9-point LRV gap — 24 for Cement grey vs 15 for Quarry Rock — means Cement grey will open up a space more effectively. A ΔE of 11.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.
