Stormy Monday vs Iron Grey
Stormy Monday (Benjamin Moore) and Iron Grey (Jotun) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 41 vs 39 — so neither will read significantly brighter or darker than the other. Where Stormy Monday leans red, Iron Grey reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 4.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
