Copper Mine vs Nocturnal Gray
Both from Benjamin Moore's palette. Copper Mine reads as pink-red, while Nocturnal Gray reads as blue-grey — two distinct hue families, not close cousins. Nocturnal Gray (LRV 14) reflects noticeably more light than Copper Mine (LRV 11), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Copper Mine runs red while Nocturnal Gray is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 37.6, 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.
