S 3005-B20G vs RAL 180-M
Where S 3005-B20G belongs to NCS's range, RAL 180-M 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. S 3005-B20G (LRV 40) reflects noticeably more light than RAL 180-M (LRV 35), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
