Swiss Blue vs RAL 610-4
Where Swiss Blue belongs to Benjamin Moore's range, RAL 610-4 is a RAL Effect color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Swiss Blue (LRV 53) reflects noticeably more light than RAL 610-4 (LRV 40), a difference of 13 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Swiss Blue vs RAL 610-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Swiss Blue on one side and RAL 610-4 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.
