Mountain Moss vs RAL 240-3
Mountain Moss (Dulux) and RAL 240-3 (RAL Effect) come from different manufacturers. Hue-wise, Mountain Moss belongs to the beige-yellow family and RAL 240-3 to the beige-greige family. Their light reflectance values are nearly the same — 26 vs 27 — so neither will read significantly brighter or darker than the other. A ΔE of 11.2 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.
