Prelude vs Sea Mariner
Prelude and Sea Mariner come from the same Sherwin-Williams collection. Prelude reads as grey, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. The 3-point LRV gap — 9 for Prelude vs 7 for Sea Mariner — means Prelude will open up a space more effectively. Where Prelude leans neutral, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 13.0 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.

5 simulated room previews — drag the slider on each to see Prelude 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.
