title: LaTeX changes colour of in-text citing with hyperref package and natbib
body: <p>I am using the <a href="https://www.ctan.org/pkg/natbib" rel="noreferrer">natbib</a> and <a href="https://www.ctan.org/pkg/hyperref" rel="noreferrer">hyperref</a> packages in my LaTeX document and would like to change the colour of the box around the hyper-referenced citations from the baseline green to a more muted colour (violet or navy blue). However, in using the suggested code to do this, I cannot get the citation link colours to change. MWE:</p>
  
  <pre><code>\usepackage[usenames,dvipsnames]{color}
  \usepackage[round]{natbib}
  \usepackage[hyperfootnotes=false]{hyperref}
  \hypersetup{
   colorlinks=false,
   citecolor=Violet,
   linkcolor=Red,
   urlcolor=Blue}
  
   \begin{document}
  
   \bibliographystyle{apsr}
   \bibliography{exp_final}
   \end{document}
  </code></pre>
  
  <p>However, when I compile (I compiled multiple times to make sure) my pdf file looks the same as if I had excluded the formatting in the <code>\hypersetup</code> (still the same green). I would also like to box the footnote citations as well.</p>
