On The Rocks vs Viaduct
Both from Sherwin-Williams's palette. On The Rocks reads as grey, while Viaduct reads as greige-grey — two distinct hue families, not close cousins. On The Rocks (LRV 62) reflects noticeably more light than Viaduct (LRV 50), a difference of 11 points that becomes especially apparent in rooms with limited natural light. On The Rocks runs neutral while Viaduct is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
