Requisite Gray vs Viaduct

Both from Sherwin-Williams's palette. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Viaduct (LRV 50) reflects noticeably more light than Requisite Gray (LRV 45), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
