Change Button Color if FrameLoaded = n

[esearing]

Is it possible to change the color of a button/movieclip (created from a Circle)when a particular frame is loaded?

Something like
onClipEvent (load){
if(_currentFrame == 5){
c= new Color(button1);
c.setRGB(0x996633);
} else {
c= new Color(button1);
c.setRGB(0x336699);
}
}
Also need it to change color on rollOver which I can do with a button but not sure how to do it with a movieClip.

Thanks in advance
