[flexcoders] Change Color of panel from a function

[timgerr]

Hello all,
I am having troubles finding information on how to change the border
color of a panel from a function, here is my code:
<mx:Panel id="editPanel" layout="absolute" width="330" height="65%"
right="10" top="128">
  <mx:Button x="122.5" y="10" click="EditMe" id="nodeEditMode"
label="Edit Mode"/>
  <mx:Label x="10" y="37" text="Name"/>
  <mx:TextInput x="10" y="63" id="node_Name" width="218"
editable="false"/>
</mx:Panel>

private function EditMe():void
{
  Not sure what to put here
}

I don't see the ability to change the color when I do editPanel. .
Thanks for the help,
timgerr
