One of the major themes in "A Clockwork Orange" is having the free will to do anything you desire ... Whether its right or wrong ...good or evil... as long as you believe in it.
Being part of the society ... you are expected to abide by the rules and regulation, and be as neat (white) as possible ... you are going to do whatever they say, dress as they say ... be as they expect you to be...
But if you have the free will to unleash whats within you ...
You'll be as real as you are!
