> **Issue:** Works well for most of the scenarios (including on-the-fly changes) and follows the accent color changes except when we start the application with accent color set to Graphite and then change accent color on-the-fly (as mentioned above). The cell focus ring remains gray. The issue seems to be with the system color returned by the type-property "**keyboardfocusindicatorcolor**" under this setting.

@prrace @prsadhuk 
The issue with the system color returned by **keyboardFocusIndicatorColor** mentioned above, persists on macOS 12.3 as well.
