Signal yellow vs S 1502-Y Color Comparison
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.

House
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. S 1502-Y returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
