Getting values selected from color picker

I would like to use colors selected by user from the color picker to generate list of colors separated by comma, so that user will be able to copy them. How can I do that?

Selected colors do not need to be saved in current topic, I only need to generate list.

With a little fiddling, I was able to come up with a solution that I believe serves your purpose. It may not be the most elegant and I invite anyone to improve on it.

Here you go:

Your color list:

%STARTSECTION{"code"}%
%JQREQUIRE{"farbtastic"}%
%ADDTOZONE{"script" requires="JQUERYPLUGIN::FARBTASTIC" text="<script type='text/javascript'> 
 var clearList = function() { $('#colorlist').val(''); };
 $(function() { 
  // Function to check if selected color is in list and if not, adds it
  var checkColor = function(theColor) { 
    var oldList = $('#colorlist').val();
    var addComma = '';
    if (oldList != '') { var addComma = ', '; }
    if (oldList.indexOf(theColor) == '-1'){
      var newList = oldList + addComma + theColor;
      $('#colorlist').val(newList);
    }
  }
  // Captures selections in farbtastic color selector
  $('#colorpicker').on('mouseup', function() {
    checkColor($('input#color').val());
  });
  // Simply selects content of color list field when clicked
  $('#colorlist')
     .focus(function () { $(this).select(); } )
     .mouseup(function (e) {e.preventDefault(); 
  });
  // Adds instructions to the color field
  $('input#color').val('Click to select colors')
 }); 
 </script>"
}%
<input type="text" id="color" name="color" value="#9eeefa" class="jqFarbtastic" />  *Your color list:* <input type='text' id='colorlist' size='70' readonly='readonly' title='Click to select color list'> <input type='button' onclick='clearList();' value=' Clear list '>
%ENDSECTION{"code"}%
