Luke’s saber changes color 3-4 times over a period of a couple of minutes on the new DVD set. Just as the Millenium Falcon escapes Tatooine and Leia witnesses the destruction of her home planet. We cut to Obi-Wan sensing the obliteration of Alderaan. Notice Luke, who’s busy training with the drone.
His saber is green.
As the scene progresses, it sort of shifts back and forth between green and blue. It looks horrible!
In general, the colors on this edition are overly saturated… You’d think that with all the changes, they would have fixed the sabers as first priority.
