Quarry Rock vs City Fog
Where Quarry Rock belongs to Benjamin Moore's range, City Fog is a Dulux color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (15 vs 15), so they'll read as similarly Dark in most lighting conditions. Quarry Rock runs green while City Fog is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
