Cole Stone vs RAL 150-M
Cole Stone (Benjamin Moore) and RAL 150-M (RAL Effect) come from different manufacturers. Cole Stone reads as greige-grey, while RAL 150-M reads as beige-greige — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 33 vs 33 — so neither will read significantly brighter or darker than the other. ΔE 4.9 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.

Cole Stone vs RAL 150-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Cole Stone on one side and RAL 150-M 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.
