Porpoise vs Passageway
Porpoise (Sherwin-Williams) and Passageway (Valspar) come from different manufacturers. Porpoise reads as greige-grey, while Passageway reads as blue-grey — two distinct hue families, not close cousins. 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 15.6 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.
Porpoise vs Passageway in Real Spaces
2 real rooms side by side. Seeing Porpoise and Passageway in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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