Window grey vs K488
Window grey (RAL Classic) and K488 (Tikkurila) come from different manufacturers. Window grey reads as blue-grey, while K488 reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 36 vs 34 — so neither will read significantly brighter or darker than the other. ΔE 3.2 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.
