Zen vs Cement grey
Zen (PPG) and Cement grey (RAL Classic) come from different manufacturers. Zen reads as blue, while Cement grey reads as grey — two distinct hue families, not close cousins. The 45-point LRV gap — 69 for Zen vs 24 for Cement grey — means Zen will open up a space more effectively. A ΔE of 34.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.

5 simulated room previews — drag the slider on each to see Zen on one side and Cement grey 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.
