Mariner vs Nautilus

Mariner and Nautilus 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 4-point LRV gap — 46 for Mariner vs 42 for Nautilus — means Mariner 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. ΔE 9.0 means they're clearly different, but not dramatically so — they'd pair well in the same room.
