LibreOffice 25.8 Help
The bundling of colour, font and format settings is possible under the concept of Theme.
Theme colours is a set of twelve colours - each colour has 5 variations computed internally, defined by their RGB-value and only the RGB-value is written to document file. A colour of an object can be defined by a reference into a colour of the Theme colours set. This reference is done by keyword or index, depending on the context.
You need to save the document with the ODF 1.3 extended format or later to use themes.
The new feature has been mainly implemented for the import and export filter with MS Office.
Display the set of available themes for the document. To apply a theme to the document, double-click on the selected theme.
The top left theme in the Available Themes area is the current applied theme.
Opens the Theme Colour Dialogue Box to define the theme name and the colours of the selected new theme.
