Antimony vs Fortitude
Both from Sherwin-Williams's palette. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (57 vs 56), so they'll read as similarly Light in most lighting conditions. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.0, 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 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Antimony vs Fortitude in Real Spaces
1 real room side by side. Antimony and Fortitude 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.

5 simulated room previews — drag the slider on each to see Antimony on one side and Fortitude 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.
