Rain Cloud vs Waterloo
Rain Cloud and Waterloo come from the same Sherwin-Williams collection. Rain Cloud reads as blue-grey, while Waterloo reads as blue — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 11 vs 13 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. ΔE 3.8 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Rain Cloud vs Waterloo in Real Spaces
2 real rooms side by side. Rain Cloud 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.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. The distinction reads clearly at room scale, making the choice between them concrete.

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.
