Outerspace vs Waterloo
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.
Outerspace vs Waterloo in Real Spaces
5 real rooms side by side. Outerspace and Waterloo are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. The distinction reads clearly at room scale, making the choice between them concrete.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

Outerspace vs Waterloo Simulated Comparison
5 simulated room previews — drag the slider on each to see Outerspace on one side and Waterloo 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.
