Green Bay vs Poseidon

Both from Sherwin-Williams's palette. Green Bay reads as blue-green, while Poseidon reads as blue — two distinct hue families, not close cousins. They have nearly identical light reflectance values (11 vs 11), 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 10.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
