Perfect Periwinkle vs Warm Stone
Both from Sherwin-Williams's palette. Perfect Periwinkle reads as blue, while Warm Stone reads as greige-grey — two distinct hue families, not close cousins. Perfect Periwinkle (LRV 23) reflects noticeably more light than Warm Stone (LRV 20), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Perfect Periwinkle 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 35.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
