Flex 4: mx | Tree how can I turn off hover and selection colors?

Question

this is the second question related to my first question:

Flex 4: mx | tree - how can I turn off the selection of elements?

I want to turn off the hover and selection colors, so when the user selects an element whose background does not change color. how is this possible?

Update

I do not want to select highlight colors and colors. the background contains an image, so it will not be useful. I need to completely disable the colors.

another update

I tried to override the Tree class, but no luck.

this is the class that overrides the tree. Grade:

package components.popups.WelcomeBack {
import mx.controls.listClasses.IListItemRenderer;
import mx.controls.Tree;

/**
 * @author ufk
 */
public class TreeNoSelection extends Tree {

     protected override function drawItem(item:IListItemRenderer,
                            selected:Boolean = false,
                            highlighted:Boolean = false,
                            caret:Boolean = false,
                            transition:Boolean = false):void
    {
        super.drawItem(item, false, false, false, transition);  
    }

}


}

and this is my actual tree component:

<?xml version="1.0" encoding="utf-8"?>
<WelcomeBack:TreeNoSelection xmlns:fx="http://ns.adobe.com/mxml/2009" 
     xmlns:s="library://ns.adobe.com/flex/spark" 
     xmlns:mx="library://ns.adobe.com/flex/mx"
     xmlns:WelcomeBack="components.popups.WelcomeBack.*" folderClosedIcon="{null}" defaultLeafIcon="{null}"
     folderOpenIcon="{null}" 
     showRoot="false"  
            allowMultipleSelection="false" allowDragSelection="false" labelField="@label">
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

<fx:Script>
    <![CDATA[
        import ItemRenderer.WelcomeBackTreeItemRenderer;
        private var _themeLibrary:Object;

        public function get themeLibrary():Object {
            return this._themeLibrary;
        }

        public function set themeLibrary(tl:Object):void {
            this._themeLibrary=tl;
            var cf:ClassFactory = new ClassFactory();
            cf.generator = ItemRenderer.WelcomeBackTreeItemRenderer;
            cf.properties = {
                _themeLibrary:this._themeLibrary
            };
            this.itemRenderer=cf;
        }

    ]]>
</fx:Script>

</WelcomeBack:TreeNoSelection>

package custom
{
    import mx.controls.Tree;
    import mx.controls.listClasses.IListItemRenderer;

    public class CustomTree extends Tree
    {
         protected override function drawItem(item:IListItemRenderer,
                                selected:Boolean = false,
