You can easily change the color with option "colorlinks",
but then the color is also printed.

Underlining or coloring without printing is not
supported by the PDF format. You can overlay the
printed text with colored non-printable annotations,
but there are several disadvantages:
* Increase of pdf file size.
* Slow rendering by AR.
* The automatic link breaking is not supported.
* It is not directly supported by hyperref, so
  the needed macros have to be written.
