Chimney vs S 7500-N
Chimney (Behr) and S 7500-N (NCS) come from different manufacturers. Chimney reads as blue-grey, while S 7500-N reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 8 vs 8 — so neither will read significantly brighter or darker than the other. Where Chimney leans blue, S 7500-N reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 5.7 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Chimney vs S 7500-N in Real Spaces
1 real room side by side. Chimney and S 7500-N 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 7500-N brings more warmth to the space, while Chimney keeps things cooler and crisper.

Chimney vs S 7500-N Simulated Comparison
5 simulated room previews — drag the slider on each to see Chimney on one side and S 7500-N 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.
