The masterpiece Matrix (one) by the Wachowski brothers asks the question: Do you want to know about the truth, real life and the hard realities - or would you rather choose to comfortably allow the deception at the "small" cost of your real freedom. The Matrix is not only a state of the art Si-Fi story - but also very real - if you get your head around it as an analogy for contemporary life.
The question is asking us whether reality, truth and ethic values is worth pursuing. The blue pill will leave us as we are, in a life consisting of habit, of things we believe we know. We are comfortable, we do not need truth to live.
The red pill is an unknown quantity. We are told that it can help us to find the truth. We don't know what that truth is, or even that the pill will help us to find it. The red pill symbolizes risk, doubt and questioning. In order to answer the question, you can gamble your whole life and world on a reality you have never experienced.
