Quartz grey vs RAL 340-4 in Real Spaces
3 real rooms side by side. Seeing Quartz grey and RAL 340-4 in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Kitchen

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

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 340-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Quartz grey on one side and RAL 340-4 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.
