Black Beauty vs Grey Blue
Black Beauty (Benjamin Moore) and Grey Blue (RAL Classic) come from different manufacturers. Black Beauty reads as grey, while Grey Blue reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 5 vs 7 — so neither will read significantly brighter or darker than the other. A ΔE of 11.8 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Black Beauty vs Grey Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Black Beauty on one side and Grey Blue 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.
