Quartz grey vs RAL 540-M
Quartz grey (RAL Classic) and RAL 540-M (RAL Effect) come from different manufacturers. Quartz grey reads as grey, while RAL 540-M reads as pink-purple — two distinct hue families, not close cousins. The 11-point LRV gap — 17 for Quartz grey vs 6 for RAL 540-M — means Quartz grey will open up a space more effectively. A ΔE of 33.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Quartz grey vs RAL 540-M in Real Spaces
3 real rooms side by side. Seeing Quartz grey and RAL 540-M in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Quartz grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Quartz grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Quartz grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Quartz grey vs RAL 540-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Quartz grey on one side and RAL 540-M 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.
