Pool Blue vs River Rouge
Both from Sherwin-Williams's palette. Hue-wise, Pool Blue belongs to the blue family and River Rouge to the grey family. Pool Blue (LRV 70) reflects noticeably more light than River Rouge (LRV 12), a difference of 59 points that becomes especially apparent in rooms with limited natural light. Pool Blue runs cool while River Rouge is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 54.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
