Cathedral Gray vs Coastline
Both from Benjamin Moore's palette. Hue-wise, Cathedral Gray belongs to the greige-grey family and Coastline to the blue-grey family. Coastline (LRV 34) reflects noticeably more light than Cathedral Gray (LRV 26), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Cathedral Gray runs red while Coastline is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 17.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
