Cosmos vs Wondrous Blue
Cosmos and Wondrous 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 21-point LRV gap — 59 for Wondrous Blue vs 38 for Cosmos — means Wondrous Blue 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 14.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Cosmos vs Wondrous Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Cosmos on one side and Wondrous Blue on the other.
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.
