RAL 720-5 vs Jamaica Bay
Where RAL 720-5 belongs to RAL Effect's range, Jamaica Bay is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Jamaica Bay (LRV 30) reflects noticeably more light than RAL 720-5 (LRV 19), a difference of 11 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
