Mount Etna vs Nouvelle White

Both from Sherwin-Williams's palette. Mount Etna reads as blue-grey, while Nouvelle White reads as grey-white — two distinct hue families, not close cousins. Nouvelle White (LRV 72) reflects noticeably more light than Mount Etna (LRV 6), a difference of 66 points that becomes especially apparent in rooms with limited natural light. Mount Etna runs cool while Nouvelle White is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 58.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
