Smooth White vs S 1502-Y
Smooth White (Jotun) and S 1502-Y (NCS) come from different manufacturers. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. The 5-point LRV gap — 64 for S 1502-Y vs 59 for Smooth White — means S 1502-Y will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.5 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Smooth White vs S 1502-Y in Real Spaces
2 real rooms side by side. Smooth White and S 1502-Y 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 1502-Y reads slightly lighter here — a subtle but real difference in how open the space feels.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The brightness difference is modest but present — S 1502-Y gives the walls a little more lift.

Smooth White vs S 1502-Y Simulated Comparison
5 simulated room previews — drag the slider on each to see Smooth White on one side and S 1502-Y 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.
