Changing TextField color / backgroundColor Dynamically?

Question

Is it possible to change the color or background color of a textfield using actionscript in a MXML file???  A simple example:
<fx:Script>
     <![CDATA[
          var changeColor:Boolean = true;
          if (changeColor == true)
               exampleText.color = '#FF000';
               exampleText.backgroundColor = '#FFFFFF';
     ]]>
</fx:Script>
<s:TextInput id="exampleText" text="Example Text" />
Neither seems to work!?!?!

@Lax - is your question answered?
UPDATE: Just noticed you are using contentBackgroundColor (was looking at the post title).
Use contentBackgroundColor and contentBackgroundAlpha.
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark" title="Home">
    <fx:Script>
        <![CDATA[
            protected function textinput1_clickHandler(event:MouseEvent):void {
                event.currentTarget.setStyle("color", "#0000ff");
                event.currentTarget.setStyle("contentBackgroundColor", 0x00ff00);
        ]]>
    </fx:Script>
    <s:TextInput contentBackgroundColor="#666666" text="Hello color filled World" click="textinput1_clickHandler(event)"/>
</s:View>
FYI keep in mind you now have access to the FXG MXML markup. This can be a quicker solution than recreating a new skin. If the contentBackgroundColor property didn't exist this is what you could have done prior to creating your own skin:
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark" title="Home"
    <fx:Script>
        <![CDATA[
            protected function textinput1_clickHandler(event:MouseEvent):void {
                event.currentTarget.setStyle("color", "#0000ff");
                backgroundColorFill.color = 0x00ff00;
        ]]>
    </fx:Script>
    <s:Group>
        <s:Rect width="100%" height="100%">
            <s:fill>
                <s:SolidColor id="backgroundColorFill" color="#00ffff"/>
            </s:fill>
        </s:Rect>
        <s:TextInput contentBackgroundAlpha="0" text="Hello color filled World" click="textinput1_clickHandler(event)"/>
    </s:Group>
</s:View>
