UltraWhite vs Viaduct
Both from Sherwin-Williams's palette. Hue-wise, UltraWhite belongs to the white-yellow family and Viaduct to the greige-grey family. UltraWhite (LRV 94) reflects noticeably more light than Viaduct (LRV 50), a difference of 43 points that becomes especially apparent in rooms with limited natural light. UltraWhite runs neutral while Viaduct is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 21.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
