Hawaiian Blue 1 vs RAL 690-6
Where Hawaiian Blue 1 belongs to Dulux's range, RAL 690-6 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. Hawaiian Blue 1 (LRV 9) reflects noticeably more light than RAL 690-6 (LRV 5), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
