Why are you modifying the hyperlinks in code? They're blue by default, turning purple when followed. And, if you want cross-references to appear & act as hyperlinks, maybe you should be using hyperlinks for those, too.

Only where the "Hyperlink" and "FollowedHyperlink" character styles are used, which they are not for cross-references.
Cross-references must be used as the text making up the hyperlink (typically a section heading or caption number) is liable to change.

Thanks
