Limestone vs Sea Mariner
Limestone and Sea Mariner come from the same Sherwin-Williams collection. Hue-wise, Limestone belongs to the grey family and Sea Mariner to the blue-grey family. The 6-point LRV gap — 13 for Limestone vs 7 for Sea Mariner — means Limestone will open up a space more effectively. Where Limestone leans neutral, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 17.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. 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.
