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.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
