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. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
