Waxed Khaki vs Concrete grey
Waxed Khaki (Dulux) and Concrete grey (RAL Classic) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 24 vs 23 — so neither will read significantly brighter or darker than the other. A ΔE of 2.5 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.

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.
