Cement grey vs River Reed
Cement grey (RAL Classic) and River Reed (Sherwin-Williams) come from different manufacturers. Cement grey reads as grey, while River Reed reads as beige-greige — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 24 vs 25 — so neither will read significantly brighter or darker than the other. ΔE 9.7 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.

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.
