Sea Urchin 2 vs RAL 810-3
Where Sea Urchin 2 belongs to Dulux's range, RAL 810-3 is a RAL Effect color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Sea Urchin 2 (LRV 28) reflects noticeably more light than RAL 810-3 (LRV 23), a difference of 5 points that becomes especially apparent in rooms with limited natural light. The ΔE 8.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
