Ayuda de LibreOffice 26.2
Crea un tema de colores.
Introduzca el nombre del tema nuevo.
Para cada uno de los nombres de color del tema, seleccione el color en la lista desplegable de colores.
LibreOffice creates 5 additional colors to the theme calculated from the main color. The calculations of the color variants are also hard coded in the theme and you cannot change them, only the main color.
Applied user defined theme is saved only in the document. To make it usable for other documents, use themes in document templates.
