Poseidon vs Raging Sea

Both from Sherwin-Williams's palette. Hue-wise, Poseidon belongs to the blue family and Raging Sea to the blue-green family. They have nearly identical light reflectance values (11 vs 14), so they'll read as similarly Dark in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 13.7, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
