Andiron vs Sea Mariner
Andiron and Sea Mariner come from the same Sherwin-Williams collection. Andiron reads as greige-grey, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 5 vs 7 — so neither will read significantly brighter or darker than the other. Where Andiron leans warm, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 14.0 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 Andiron 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.
