Fortitude vs Guild Grey

Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. ΔE 4.4 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Fortitude vs Guild Grey in Real Spaces
1 real room side by side. Fortitude and Guild Grey 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.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Guild Grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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