Cotton vs Sea Mariner
Cotton and Sea Mariner come from the same Sherwin-Williams collection. Hue-wise, Cotton belongs to the beige-greige family and Sea Mariner to the blue-grey family. The 76-point LRV gap — 83 for Cotton vs 7 for Sea Mariner — means Cotton will open up a space more effectively. Where Cotton leans warm, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 63.0 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.
