Resolute Blue vs Vast Sky
Resolute Blue and Vast Sky come from the same Sherwin-Williams collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 15-point LRV gap — 55 for Vast Sky vs 40 for Resolute Blue — means Vast Sky 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 10.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
