Regale Blue vs Warm Stone

Both from Sherwin-Williams's palette. Hue-wise, Regale Blue belongs to the blue family and Warm Stone to the greige-grey family. Regale Blue (LRV 42) reflects noticeably more light than Warm Stone (LRV 20), a difference of 22 points that becomes especially apparent in rooms with limited natural light. Regale Blue 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 38.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
