Mystere vs French Gray
Mystere (Behr) and French Gray (Farrow & Ball) come from different manufacturers. Hue-wise, Mystere belongs to the grey family and French Gray to the beige-greige family. The 19-point LRV gap — 43 for French Gray vs 25 for Mystere — means French Gray will open up a space more effectively. Where Mystere leans red, French Gray reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 20.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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.
