Cosmos vs Passageway
Cosmos (Sherwin-Williams) and Passageway (Valspar) come from different manufacturers. Cosmos reads as blue, while Passageway reads as blue-grey — two distinct hue families, not close cousins. The 24-point LRV gap — 38 for Cosmos vs 14 for Passageway — means Cosmos will open up a space more effectively. A ΔE of 24.7 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 Passageway Simulated Comparison
5 simulated room previews — drag the slider on each to see Cosmos on one side and Passageway 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.
