LibreOffice 25.8 Help
Creates a colour theme.
Enter the name of the new theme.
For each of the theme named colour, select the colour in the colour drop-down list.
LibreOffice creates 5 additional colours to the theme calculated from the main colour. The calculations of the colour variants are also hard coded in the theme and you cannot change them, only the main colour.
Applied user defined theme is saved only in the document. To make it usable for other documents, use themes in document templates.
