Page numbers

You could have asked this in your first post instead of duplicating multiple main posts.

When you set the color of a page number, it is replicated throughout the entire document. If you want a page whose page number is a specific color, and is not replicated throughout the document, then you need to insert a section and change the page number color on it alone. For subsequent sections (and their pages), visit Document > Section and uncheck Match previous section so that your special page number treatment will not be replicated.
