Shale vs Black grey
Shale is a Benjamin Moore color while Black grey comes from RAL Classic. Shale reads as greige-grey, while Black grey reads as blue-grey — two distinct hue families, not close cousins. At LRV 50 vs 6, Shale will read as the brighter of the two — a 44-point gap that matters most in north-facing or low-light rooms. At ΔE 56.9, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. 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.
