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.

Digital color is approximate.
