Exploring Luke's Hero Journey to Bespin
Luke Skywalker is our hero of the Rebel Alliance throughout STAR WARS Original Trilogy. His journey takes him from the innocent farm boy of A New Hope, to the hardened trained master of Return of the Jedi. You can see his development visually as his clothing changes to reflect his development as a character.
George Lucas fashioned the original Star Wars Trilogy after the “monomyth'' from Joseph Campbell’s The Hero with A Thousand Faces.
Christopher Vogler later adapted this "Hero's Journey" into a 12 part story structure, and its interesting to see Luke's struggles and "Ordeals" displayed in the clothing he wore in the films.
From the innocence of white in his "Call to Adventure" to the seriousness of black as he returns from his ordeals, it is appropriate that Luke’s attire in The Empire Strikes Back is somewhere in between.
Luke's fight with Darth Vader at the end of the second film showcases "The Ordeal" in Campbell's journey for the hero.
Vogler describes “The Ordeal” as:
...This is the high-point of the Hero's story and where everything he holds dear is put on the line. If he fails, he will either die or life as he knows it will never be the same again.
