Fiery Opal vs Nocturnal Gray
Both from Benjamin Moore's palette. Hue-wise, Fiery Opal belongs to the pink-red family and Nocturnal Gray to the blue-grey family. They have nearly identical light reflectance values (16 vs 14), so they'll read as similarly Dark in most lighting conditions. Fiery Opal 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 54.2, the contrast is hard to miss.
