/**

+ * <p>ColorPicker provides a simple color palette for choosing colors. The picker can be rendered to any container.
+ * The available default to a standard 40-color palette; this can be customized with the {@link #colors} config.</p>
+ * <p>Typically you will need to implement a handler function to be notified when the user chooses a color from the
+ * picker; you can register the handler using the {@link #select} event, or by implementing the {@link #handler}
+ * method.</p>
+ * <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){
+ // do something with selColor
+});
+</code></pre>
+ * {@img Ext.picker.Color/Ext.picker.Color.png Ext.picker.Color component}
+ *
+ * @constructor
+ * Create a new ColorPicker
+ * @param {Object} config The config object
+ *
+ * @xtype colorpicker
