Perle Noir vs Sea Mariner
Both from Sherwin-Williams's palette. Perle Noir reads as grey, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (8 vs 7), so they'll read as similarly Dark in most lighting conditions. Perle Noir runs neutral while Sea Mariner is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
