Mexican Sand vs Mount Etna

Both from Sherwin-Williams's palette. Mexican Sand reads as beige-greige, while Mount Etna reads as blue-grey — two distinct hue families, not close cousins. Mexican Sand (LRV 33) reflects noticeably more light than Mount Etna (LRV 6), a difference of 27 points that becomes especially apparent in rooms with limited natural light. Mexican Sand runs warm while Mount Etna is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 40.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
