Ironclad vs Porpoise
Ironclad and Porpoise come from the same Sherwin-Williams collection. Ironclad reads as grey, while Porpoise reads as greige-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 11 vs 13 — so neither will read significantly brighter or darker than the other. Where Ironclad leans neutral, Porpoise reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 3.7 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
