Catalina Blue vs Rhine River
Both from Benjamin Moore's palette. Catalina Blue reads as blue-green, while Rhine River reads as blue-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (48 vs 47), so they'll read as similarly Medium in most lighting conditions. Catalina Blue runs cool while Rhine River is decidedly green and blue, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
