Modern Gray vs Sea Mariner
Modern Gray and Sea Mariner come from the same Sherwin-Williams collection. Modern Gray reads as beige-greige, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. The 56-point LRV gap — 62 for Modern Gray vs 7 for Sea Mariner — means Modern Gray will open up a space more effectively. Where Modern Gray leans warm, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 53.6 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Modern Gray vs Sea Mariner Simulated Comparison
5 simulated room previews — drag the slider on each to see Modern Gray on one side and Sea Mariner on the other.
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.
