You will also have to allocate the colors using the 
gtk.gdk.Colormap.alloc_color() method

In addition I think you have to catch the enter and leave notify events 
on the EventBox and set the state of the Label accordingly. For example 
something like:

def ene_cb(eb, ev):
  eb.get_child().set_state(gtk.STATE_PRELIGHT)
  return True

def lne_cb(eb, ev):
  eb.get_child().set_state(gtk.STATE_NORMAL)
  return True

E.connect('enter-notify-event', ene_cb)
E.connect('leave-notify-event', lne_cb)

might work for you.
