Cobalt Stone vs Passageway
Cobalt Stone (PPG) and Passageway (Valspar) come from different manufacturers. Hue-wise, Cobalt Stone belongs to the blue family and Passageway to the blue-grey family. Their light reflectance values are nearly the same — 14 vs 14 — so neither will read significantly brighter or darker than the other. A ΔE of 38.8 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Cobalt Stone vs Passageway Simulated Comparison
5 simulated room previews — drag the slider on each to see Cobalt Stone 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.
