Granite Boulder vs Narrow Lane
Granite Boulder (Behr) and Narrow Lane (Dulux) come from different manufacturers. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 42 vs 41 — so neither will read significantly brighter or darker than the other. Where Granite Boulder leans yellow, Narrow Lane reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.0 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
