Ironclad vs Sea Mariner
Both from Sherwin-Williams's palette. Ironclad reads as grey, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. Ironclad (LRV 11) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Ironclad runs neutral while Sea Mariner is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 14.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
