Dark mode is not available for LyX on Windows, Qt does not support it
there. I have searched on the web on how to deal with it and found some
workaround here and there but nothing official and it did seem like a lot
of work. Maybe one day some LyX dev will feel like doing it, but for now
consider it not existent. You can make one thing dark though, the work
area, but menus, toolbars and messages pane and other stuff you can show on
the bottom can not be made dark.
