I'm not an "original" fan....I was born in 1987, but I am a huge supporter in seeing the original original trilogy released. However, I was watching the original trailer the other day and noticed that Darth Vader's lightsaber was white. I soon found out that all the lightsabers in the original film were white. When did the lightsabers get colourized? Just wondering because I also noticed in the trailer for Return of the Jedi that the lightsabers were red and blue. Does anyone know when the change was made and why?
