Smoke Grey vs Steel Symphony 3
Both from Dulux's palette. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Steel Symphony 3 (LRV 35) reflects noticeably more light than Smoke Grey (LRV 30), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 4.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
