Zen vs Grey Blue
Zen (Behr) and Grey Blue (RAL Classic) come from different manufacturers. Zen reads as green-grey, while Grey Blue reads as blue-grey — two distinct hue families, not close cousins. The 38-point LRV gap — 46 for Zen vs 7 for Grey Blue — means Zen will open up a space more effectively. A ΔE of 43.8 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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