Dress Blues vs Warm Stone
Both from Sherwin-Williams's palette. Hue-wise, Dress Blues belongs to the blue family and Warm Stone to the greige-grey family. Warm Stone (LRV 20) reflects noticeably more light than Dress Blues (LRV 5), a difference of 15 points that becomes especially apparent in rooms with limited natural light. Dress Blues runs cool while Warm Stone is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 38.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
