Ecru vs Sea Mariner
Ecru and Sea Mariner come from the same Sherwin-Williams collection. Hue-wise, Ecru belongs to the beige family and Sea Mariner to the blue-grey family. The 44-point LRV gap — 51 for Ecru vs 7 for Sea Mariner — means Ecru will open up a space more effectively. Where Ecru leans warm, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 53.9 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.
