*
var cp = new Ext.ColorPalette({value:'993300'}); // initial selected color
cp.render('my-div');
cp.on('select', function(palette, selColor){
// do something with selColor
});
* @constructor
* Create a new ColorPalette
* @param {Object} config The config object
* @xtype colorpalette

var cp = new Ext.ColorPalette();
