Hello FrontPageNewUser77,
I'm also a new Front Page user. (Front Page 2003)
I'm creating some hyperlinks on my web site as well, and I've found that if
I highlight (select) my hyperlink (linkbar) and then go to Format>Font,
instead of Format>Theme, then I get all the options I want in terms of font
size, boldness, colour, etc. including the customization of individual
colours.
I believe the "Theme" option is more commonly used as a preset set of styles
that you've already created, but on a one-off basis, by going to the "Font"
selection, you should be able to customize each hyperlink (link bar)
individually.
I wish you the best of success with this. Please let us know how it worked
out for you!
Regards,
Karen
