Lagoon vs River Rouge
Lagoon and River Rouge come from the same Sherwin-Williams collection. Lagoon reads as blue, while River Rouge reads as grey — two distinct hue families, not close cousins. The 9-point LRV gap — 20 for Lagoon vs 12 for River Rouge — means Lagoon will open up a space more effectively. Where Lagoon leans cool, River Rouge reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 33.7 puts these firmly in different territory — two distinct design choices rather than close alternatives.
