Outerspace vs Waterloo

OuterspaceSherwin-WilliamsvsWaterlooSherwin-WilliamsΔE 5.0 — Noticeable difference

Both from Sherwin-Williams's palette. Outerspace reads as blue-grey, while Waterloo reads as blue — two distinct hue families, not close cousins. They have nearly identical light reflectance values (12 vs 13), so they'll read as similarly Dark in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

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.
