Revision history [back]

Status from earlier this year.
The feature request is still open.

In the code it looks like it is determined from the operating system:

// If our window text is lighter than the window background, assume the theme is dark.
QPalette gui_pal = qApp->palette();
prefs_set_gui_theme_is_dark(gui_pal.windowText().color().value() > gui_pal.window().color().value());

Are you looking for a preference to over ride this?
