Black grey vs Purple Passage
Black grey (RAL Classic) and Purple Passage (Sherwin-Williams) 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 6-point LRV gap — 12 for Purple Passage vs 6 for Black grey — means Purple Passage will open up a space more effectively. A ΔE of 25.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.
