Hibernate vs Sea Mariner
Both from Sherwin-Williams's palette. Hue-wise, Hibernate belongs to the grey family and Sea Mariner to the blue-grey family. Hibernate (LRV 38) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 32 points that becomes especially apparent in rooms with limited natural light. Hibernate runs neutral while Sea Mariner is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 38.9, 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.
