Gesso vs RAL 840-1 in Real Spaces
4 real rooms side by side. Gesso and RAL 840-1 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room

Gesso vs RAL 840-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Gesso on one side and RAL 840-1 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.
