Big Chill vs Zircon
Both from Sherwin-Williams's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Big Chill (LRV 62) reflects noticeably more light than Zircon (LRV 59), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.1, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Big Chill vs Zircon in Real Spaces
2 real rooms side by side. Big Chill and Zircon 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

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.
