CoastlineBenjamin MoorevsGothic ArchBenjamin MooreΔE 13.8 — Distinct difference

Both from Benjamin Moore's palette. Coastline reads as blue-grey, while Gothic Arch reads as greige-grey — two distinct hue families, not close cousins. Coastline (LRV 34) reflects noticeably more light than Gothic Arch (LRV 31), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Coastline runs blue while Gothic Arch is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 13.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
