Metropolis vs Mount Etna

Metropolis and Mount Etna come from the same Sherwin-Williams collection. Metropolis reads as grey, while Mount Etna reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 8 vs 6 — so neither will read significantly brighter or darker than the other. Where Metropolis leans neutral, Mount Etna reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 10.4 puts these firmly in different territory — two distinct design choices rather than close alternatives.
