I believe you could do something like that (borrowed from the LaTeX Wikibook):
#+LATEX_HEADER: \hypersetup{
#+LATEX_HEADER:     colorlinks=true,        % false: boxed links; true: colored links
#+LATEX_HEADER:     linkcolor=red,          % color of internal links (change box color with linkbordercolor)
#+LATEX_HEADER:     citecolor=green,        % color of links to bibliography
#+LATEX_HEADER:     filecolor=cyan,         % color of file links
#+LATEX_HEADER:     urlcolor=magenta        % color of external links
#+LATEX_HEADER: }

Hi,

In my Beamer presentation the hyperlinks, all URLs, appear as normal
text and can only be identified by the change in the cursor when the
mouse moves over them.

How can I change the colour of such links?

I have already several lines such as

  #+LATEX_HEADER: \setbeamercolor{title}{fg=mFubMainGreen}

to tweak the appearance, but wasn't able to find an appropriate keyword
for URLs.

Cheers,

Loris
