Cornwall Slate vs Dusty Heather

Cornwall Slate and Dusty Heather come from the same Sherwin-Williams collection. Cornwall Slate reads as grey, while Dusty Heather reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 29 vs 28 — so neither will read significantly brighter or darker than the other. Where Cornwall Slate leans neutral, Dusty Heather reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 17.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Digital color is approximate.

Before committing to either color, test physical samples in your own space under the light you actually live with.
