S 4500-N vs RAL 850-4
S 4500-N (NCS) and RAL 850-4 (RAL Effect) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 27 vs 27 — so neither will read significantly brighter or darker than the other. ΔE 3.6 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

5 simulated room previews — drag the slider on each to see S 4500-N on one side and RAL 850-4 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.
