Charcoal Blue vs Warm Stone
Both from Sherwin-Williams's palette. Hue-wise, Charcoal Blue belongs to the blue-grey family and Warm Stone to the greige-grey family.

Charcoal Blue runs cool while Warm Stone is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 30.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
