The Themes section allows you to customize interface appearance and colors.
The colors for each editor can be set separately by simply selecting the editor you wish to change in the multi-choice list at the left, and adjusting colors as required. Notice that changes appear in real-time on your screen. In addition, details such as the dot size in the 3D View or the Graph Editor can also be changed.
Themes use Blender’s preset system to save a theme.
This will save the theme to an XML file in the
./scripts/presets/interface_theme/ subdirectory of one of
the configuration directories.
