My app calls Color.IsDarkMode for custom controls and otherwise uses Color.TextColor etc. to use system colours where appropriate. It responds correctly to Dark Mode being turned on or off on my machine running Catalina.
However, a user has just reported that on his Catalina machine with General Appearance setting on Auto using Night Shift, his desktop is not in Dark Mode, but the App is displaying in Dark Mode.
Anyone know what’s going on?
