Mercurial vs Night Watch
Both from Sherwin-Williams's palette. Mercurial reads as greige-grey, while Night Watch reads as blue-grey — two distinct hue families, not close cousins. Mercurial (LRV 61) reflects noticeably more light than Night Watch (LRV 4), a difference of 57 points that becomes especially apparent in rooms with limited natural light. Mercurial runs warm while Night Watch is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 60.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
