Set element's Additional classes to colorize and display mode to either Icon or Icon and value.

Add to Custom CSS to hide the icon image.

Code:

.colorize .icon img {
  visibility: hidden;
}

Add to Custom JavaScript:

Code:

$(function(){
  $('.colorize').each(function(_, el) {
    var $el = $(el), addr = $el.data('object'), icon = $el.find('.icon');
    
    grp.listen(addr, function(obj) {
      var val = obj.value || 0;
      val = Math.round(2.55 * (100 - val));
      icon.css('background-color', 'rgb(' + val + ', 255, ' + val + ')');
    });
  });
});
