Bitter Chocolate 4 vs RAL 840-3
Bitter Chocolate 4 (Dulux) and RAL 840-3 (RAL Effect) come from different manufacturers. Bitter Chocolate 4 reads as grey, while RAL 840-3 reads as greige-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 47 vs 46 — so neither will read significantly brighter or darker than the other. ΔE 4.7 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.

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