Cement grey vs Aquarium
Cement grey (RAL Classic) and Aquarium (Sherwin-Williams) come from different manufacturers. Cement grey reads as grey, while Aquarium reads as blue — two distinct hue families, not close cousins. The 8-point LRV gap — 32 for Aquarium vs 24 for Cement grey — means Aquarium will open up a space more effectively. A ΔE of 33.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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.
