Signal grey vs K488
Signal grey (RAL Classic) and K488 (Tikkurila) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 35 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.

Signal grey vs K488 Simulated Comparison
5 simulated room previews — drag the slider on each to see Signal grey on one side and K488 on the other.
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.
