Nocturne vs Prelude

Both from Sherwin-Williams's palette. Nocturne reads as greige-grey, while Prelude reads as grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (8 vs 9), so they'll read as similarly Dark in most lighting conditions. Nocturne runs warm while Prelude is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 4.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
