Sienna vs Black grey
Sienna (Benjamin Moore) and Black grey (RAL Classic) come from different manufacturers. Sienna reads as pink-red, while Black grey reads as blue-grey — two distinct hue families, not close cousins. The 3-point LRV gap — 10 for Sienna vs 6 for Black grey — means Sienna will open up a space more effectively. A ΔE of 35.7 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.

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.
