[MX] setRGB inside btn

hey everyone!
Is it possible to use setRGB inside a btn?
I have a buttom that has a textfield and a background.
I want to change only the color of the textfield!

here is the code i`m using:


function AbtnPress() {
	for (var i=1; i<8; i++) {
		var btn = _root.A["btnA0"+i];
		if (btn == this) {
			var visitedcolor = new Color(this);
			visitedcolor.setRGB(0xFFFFFF);
		}
	}
}
	for (var i=1; i<8; i++) {
		_root.A["btnA0"+i].onPress = AbtnPress;
	}

thanks
