Summer Medley 4 vs RAL 670-2
Where Summer Medley 4 belongs to Dulux's range, RAL 670-2 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. Summer Medley 4 (LRV 72) reflects noticeably more light than RAL 670-2 (LRV 58), a difference of 14 points that becomes especially apparent in rooms with limited natural light. The ΔE 9.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
