title: Preserving color of text piped through "less" or "more"
body: <p>Certain commands produce text in color for readability.</p>
  
  <p>I'm using Linux.  For example when I'm using <code>rak</code> or <code>hg diff</code>
  the output is in color for better readability.</p>
  
  <p>However when I pipe the output through <code>less</code></p>
  
  <pre><code>hg diff | less
  </code></pre>
  
  <p>the colors are lost.</p>
  
  <p>How do I preserve the color?</p>
  
  <p>Thanks!</p>
