Alloy vs Terrain
Alloy and Terrain come from the same Sherwin-Williams collection. Alloy reads as grey, while Terrain reads as greige-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 25 vs 23 — so neither will read significantly brighter or darker than the other. Where Alloy leans neutral, Terrain reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 4.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

5 simulated room previews — drag the slider on each to see Alloy on one side and Terrain on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
