S 1500-N vs Big Chill in Real Spaces
2 real rooms side by side. S 1500-N and Big Chill 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. S 1500-N brings more warmth to the space, while Big Chill keeps things cooler and crisper.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Big Chill reads more restrained here, while S 1500-N adds a sense of enclosure and warmth.

S 1500-N vs Big Chill Simulated Comparison
5 simulated room previews — drag the slider on each to see S 1500-N on one side and Big Chill 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.
