I believe you could do something like that (borrowed from the LaTeX Wikibook
<https://en.wikibooks.org/wiki/LaTeX/Hyperlinks#Customization>):
#+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: }
