Heron Plume vs Sea Mariner
Both from Sherwin-Williams's palette. Heron Plume reads as beige-greige, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. Heron Plume (LRV 75) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 69 points that becomes especially apparent in rooms with limited natural light. Heron Plume runs warm while Sea Mariner is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 59.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
