title: Get background-color in #000 format and not RGB
body: <p>With this code, I get the RGB color of any TD in my table :</p>
  
  <pre><code>alert($(this).css('background-color'));
  </code></pre>
  
  <p>the result is :</p>
  
  <blockquote>
    <p>rgb(0, 255, 0)</p>
  </blockquote>
  
  <p>Is it possible with jquery to obtain the #000 format or have I to use a function to transform the rgb in #000 format ?</p>
  
  <p>Thanks in advance for your help</p>
