How to change color of a textArea at runtime?

I am using a TextArea in my application, and wish to change the font color of textArea at runtime based on certain conditions? I am using the following code in a function

resultText.setStyle("color", 0x842D22). However, this does not work, and gives me an exception at runtime Cannot Access property of null object reference.

setStyle does not seem to work with textArea . please advise.

See if this example helps you:

 <?xml version="1.0" encoding="utf-8"?>
   <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
    <![CDATA[
        public var flag:Boolean = true;
        public function clickHandler():void{
         if(flag)
          {resultText.setStyle("color","red");
           }
           else
           {
           resultText.setStyle("color","blue");
           }    
          flag = !flag;
        }
        ]]>
</mx:Script><mx:TextArea x="59" y="104" id="resultText"/>
<mx:Button id="colorChangeButton" label="Change Color" click="clickHandler()" x="83" y="180" /></mx:Application>
