Grey aluminium vs Piazza
Grey aluminium (RAL Classic) and Piazza (Tikkurila) come from different manufacturers. Grey aluminium reads as grey, while Piazza reads as beige-greige — two distinct hue families, not close cousins. The 36-point LRV gap — 65 for Piazza vs 29 for Grey aluminium — means Piazza will open up a space more effectively. A ΔE of 29.3 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.
