     * The available default to a standard 40-color palette; this can be customized with the {@link #colors} config.</p>

     * picker; you can register the handler using the {@link #select} event, or by implementing the {@link #handler}

     * <p>Here's an example of typical usage:</p>
     * <pre><code>var cp = new Ext.picker.Color({
        value: '993300',  // initial selected color
        renderTo: 'my-div'

    cp.on('select', function(picker, selColor){
