Relic Bronze vs Thunder Gray
Both from Sherwin-Williams's palette. Hue-wise, Relic Bronze belongs to the beige family and Thunder Gray to the grey family. Relic Bronze (LRV 17) reflects noticeably more light than Thunder Gray (LRV 9), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Relic Bronze runs warm while Thunder Gray is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 31.8, the contrast is hard to miss.
