title: Pandoc conversion to PDF not providing colored hyptertext links
body: <p>Consider the following snippet of a PDF generated from <code>pandoc</code> by way of <code>latex</code>.</p>
  
  <p><a href="https://i.stack.imgur.com/0QT4A.png" rel="noreferrer"><img src="https://i.stack.imgur.com/0QT4A.png" alt=""></a></p>
  
  <p>Were you able to identify the hypertext links in there?  Neither was I...  It turns out that the <em>second</em> <code>Kaplan Meier</code> has a fully functional link to an external site.  But how do we divine that?</p>
  
  <p>Note that the following option is already in place in the <code>pandoc</code> <em>preamble</em> - without which the hyperlink would not work at all:</p>
  
  <pre><code>link-citations: true
  </code></pre>
  
  <p>Short of a "real" solution I'll need to hack something to make hints for the links -  possibly via font manipulations.</p>
