Conditional colours for chapters
When we work with chapters and styles, sometimes we have a different thematic colour by chapter. It would be very interesting to define one or several conditional chapter colours for a section. We define the "Conditional chapter colour" in styles and depending on the page, these colours change. So, there is no need to create multiple styles with same parameters but different colours within the document or there is no need to split the document to play with these different parameters. Everything is in the same document and it is easier if we need to change the colour palette.
