Fortitude vs Zircon
Both are Sherwin-Williams colors. These are both greys, so the question isn't which hue to choose — it's where within grey to land. At LRV 59 vs 56, Zircon will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. They share a neutral quality — useful to know if you're layering them in the same space. With a ΔE of 1.6, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Fortitude vs Zircon in Real Spaces
1 real room side by side. Fortitude 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.

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.
