title: JavaScript eyedropper (tell color of pixel under mouse cursor)
body: <p>I am looking for an "<strong>eyedropper</strong>" tool, that gives me the hex value of the pixel the mouse cursor is under, in JavaScript for a CMS.</p>
  
  <p>For Firefox, there is the excellent <a href="http://www.colorzilla.com/firefox/screenshots.html" rel="noreferrer"><strong>ColorZilla</strong></a> extension that does exactly that. However, it's FF only of course, and I would really like to deliver the tool along with the CMS.</p>
  
  <p>A dutch developer has had the <a href="http://youngdutchdesign.com/moodrop-mootools-eyedropper-tool" rel="noreferrer"><strong>very clever idea</strong></a> of using a combination of Ajax and PHP's <code>imagecolorat()</code> to find out the Pixel colour on an image. <strong>But that limits the range to images I can access server side</strong>, and I'm really dreaming of a universal tool. </p>
  
  <p>I will work with one of these approaches, but would much prefer a cross-browser, Javascript or Flash based way that requires no server-side fiddling and no installing of extensions.</p>
  
  <p>I am also interested in any IE specific solutions that do what ColorZilla can do - I could live with supporting IE and FF only, though a cross browser solution would of course be ideal.</p>
