Flagstone vs Smoky Quartz

Flagstone and Smoky Quartz come from the same PPG collection. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 14-point LRV gap — 41 for Flagstone vs 27 for Smoky Quartz — means Flagstone will open up a space more effectively. A ΔE of 14.7 puts these firmly in different territory — two distinct design choices rather than close alternatives.
