Rust vs Grey Blue
Rust (Benjamin Moore) and Grey Blue (RAL Classic) come from different manufacturers. Rust reads as beige-pink, while Grey Blue reads as blue-grey — two distinct hue families, not close cousins. The 12-point LRV gap — 20 for Rust vs 7 for Grey Blue — means Rust will open up a space more effectively. A ΔE of 54.4 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.

Rust vs Grey Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Rust 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.
