Mortar vs Sea Mariner
Mortar and Sea Mariner come from the same Sherwin-Williams collection. Mortar reads as beige-greige, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. The 67-point LRV gap — 74 for Mortar vs 7 for Sea Mariner — means Mortar will open up a space more effectively. Where Mortar leans warm, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 59.0 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.
