I agree that *args makes the code non-obvious.  However, if **kwargs
is used instead:

  def str(obj, **kwargs):
    return obj.__str__(**kwargs)

  class Color:
    msg = {'en':['red', 'green', 'blue'], 'de':['rot','grün','blau']}
    def __str__(self, language='en'):
      return self.msg[language][self.value]

  red = Color(0)

  print str(red, language='de')

I find that quite readable.
