Icelandic vs Mercurial

Both from Sherwin-Williams's palette. Icelandic reads as blue, while Mercurial reads as greige-grey — two distinct hue families, not close cousins. Icelandic (LRV 67) reflects noticeably more light than Mercurial (LRV 61), a difference of 6 points that becomes especially apparent in rooms with limited natural light. Icelandic runs cool while Mercurial is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 10.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
