Themes can be selected in LOOT’s settings dialog. Two themes are provided with LOOT: the default theme and a dark theme.

If you’re running LOOT on Linux with a dark system theme, then depending on your system configuration you may get better results with LOOT’s default theme than with its dark theme.

Additional themes may be installed in the themes directory in LOOT’s application data directory (at %LOCALAPPDATA%\LOOT on Windows). A theme is defined by a single <theme name>.theme.qss Qt Style Sheet file.
