A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

S 3502-B vs Let it Rain Simulated Comparison
5 simulated room previews — drag the slider on each to see S 3502-B on one side and Let it Rain 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.
