Marine vs Underseas
Both from Sherwin-Williams's palette. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. Marine (LRV 36) reflects noticeably more light than Underseas (LRV 25), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Marine runs cool while Underseas is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 9.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
