Coquina vs Endless Sea
Both from Sherwin-Williams's palette. Coquina reads as grey, while Endless Sea reads as blue — two distinct hue families, not close cousins.

Coquina runs neutral while Endless Sea is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 33.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Digital color is approximate.
