Traditional Blue vs RAL 650-3 in Real Spaces

5 simulated room previews — drag the slider on each to see Traditional Blue on one side and RAL 650-3 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.
