the background foreground alas, neither have worked. doing wrong?

in itemstatechanged() should compare source of event , not event itself. example:

  if(event.getsource().equals(red)){     textfield.setbackground(color.red);   } 

you can use actionlistener on radio buttons. see how use radio buttons example.
