Shale vs Silk Grey
Where Shale belongs to Benjamin Moore's range, Silk Grey is a RAL Classic color. Shale reads as greige-grey, while Silk Grey reads as grey — two distinct hue families, not close cousins. Shale (LRV 50) reflects noticeably more light than Silk Grey (LRV 47), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. 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.
