Limestone vs Passageway
Limestone (Sherwin-Williams) and Passageway (Valspar) come from different manufacturers. Hue-wise, Limestone belongs to the grey family and Passageway to the blue-grey family. Their light reflectance values are nearly the same — 13 vs 14 — so neither will read significantly brighter or darker than the other. A ΔE of 15.1 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.

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