River Rouge vs Underseas
River Rouge and Underseas come from the same Sherwin-Williams collection. River Rouge reads as grey, while Underseas reads as green-grey — two distinct hue families, not close cousins. The 14-point LRV gap — 25 for Underseas vs 12 for River Rouge — means Underseas will open up a space more effectively. Where River Rouge leans warm, Underseas reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 26.4 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.
