Poolside Blue vs Poseidon

Poolside Blue and Poseidon come from the same Benjamin Moore collection. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 8-point LRV gap — 40 for Poolside Blue vs 31 for Poseidon — means Poolside Blue will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. ΔE 6.9 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
