Coastline vs Shiitake Mushroom
Both from Benjamin Moore's palette. Coastline reads as blue-grey, while Shiitake Mushroom reads as beige-greige — two distinct hue families, not close cousins. They have nearly identical light reflectance values (34 vs 34), so they'll read as similarly Medium in most lighting conditions. Coastline runs blue while Shiitake Mushroom is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 23.7, 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.
