Open Seas vs Secure Blue

Open Seas and Secure Blue come from the same Sherwin-Williams collection. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 17-point LRV gap — 39 for Open Seas vs 22 for Secure Blue — means Open Seas will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 16.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.
