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.

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.
