Radio Button Group label color?

[Joel_Herrera]

Hey folks I was trying to change the color of my radio button labels to white, however they are not individual radio buttons, it is a group of radio buttons. This is the code if anyone can help me out that would be great!
private function createRadioButton(rbLabel:String, rbg:RadioButtonGroup, posX:int):void {
var rb:RadioButton = new RadioButton();
rb.label = rbLabel;
rb.group = rbg;
rb.width = 200;
rb.move(posX, currHeight);
currHeight += verticalSpacing;
question.addChild(rb);
}
