Aruba Blue vs Poseidon

Both are Benjamin Moore colors. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 31 vs 21, Poseidon will read as the brighter of the two — a 10-point gap that matters most in north-facing or low-light rooms. They share a blue quality — useful to know if you're layering them in the same space. At ΔE 10.5, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
