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.

Digital color is approximate.
