Ash Blue vs RAL 660-3
Ash Blue (Benjamin Moore) and RAL 660-3 (RAL Effect) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 3-point LRV gap — 30 for Ash Blue vs 27 for RAL 660-3 — means Ash Blue will open up a space more effectively. ΔE 3.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Ash Blue vs RAL 660-3 Simulated Comparison
5 simulated room previews — drag the slider on each to see Ash Blue on one side and RAL 660-3 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.
