Mariner vs Rockweed

Mariner and Rockweed come from the same Sherwin-Williams collection. Hue-wise, Mariner belongs to the blue family and Rockweed to the grey family. The 42-point LRV gap — 46 for Mariner vs 4 for Rockweed — means Mariner will open up a space more effectively. Where Mariner leans cool, Rockweed reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 59.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.
