Here are some observations I made in Scribus regarding HTML import and this different style for links in the text. This is not the problem John was having, since he was working with PDFs.
It's very hard to figure out where this blue font color is located. It doesn't seem to be a separate style, but perhaps a color applied on top of the style created at import. What I found was that there is a HTML Default paragraph style which is created. Where there are links, this is blue, but the style is applied elsewhere and the text is not blue. If you look at HTML Default in the style editor, its color is black. It seemed that the easiest way to eliminate the color was to highlight the affected text, switch the style to something else, HTML_p for example, then immediately switch it back to HTML Default, at which time the color becomes black.
