title: What does highlighted colors in Sublime Text 2 signify?
body: <p>I have this code in a file:</p>
  
  <pre><code>background: -moz-linear-gradient(red, orange, yellow, green, blue, indigo, violet);
  </code></pre>
  
  <p>Sublime Text 2 seems to highlight the background of <code>indigo</code> and <code>violet</code> with a light blue color:</p>

  <p>I've tried out some more colors and most of them like <code>chocolate</code>, <code>aliceblue</code>, <code>pink</code> etc get highlighted but some others like <code>maroon</code>, <code>teal</code>, <code>silver</code> etc doesn't.</p>
  
  <p>What does the blue highlight mean?</p>
