Yes, that’s what I mean. The title bar should match dark/light colors. (But the trouble is that I’m not sure if this color can be dynamic, because Blender is Direct UI, which defines all colors that can be defined through an xml file - except for the title bar).
I’m not sure if the title bar can match the individual colors, white, dark grey, light grey…etc.
As for what you said, the question of activated windows and inactive windows, on Windows, the difference can be ignored. Since the Windows 10 era, the focus/unfocus window title bar of modern UI, the difference is the title bar text color.
In the Windows 11 era, if the title bar of the modern UI and the title bar of the focused/unfocused window use the Mica material, the focused window will be Mica, and the unfocused window will be dark gray/white.
Dark grey/white if ThemeResource AppBackgroundColor.
can you find the difference between active/inactive tittle bar？
so forget it
