The terms, popularized in science fiction culture, are derived from the 1999 film The Matrix. In the film, the main character Neo is offered the choice between a red pill and a blue pill by rebel leader Morpheus. The red pill would free him from the enslaving control of the machine - generated dream world and allow him to escape into the real world, but living the "truth of reality '' is harsher and more difficult; on the other hand, the blue pill would lead him back to stay in the comfortable simulated reality of the Matrix.
