Or he wanted to do a special colorization ala Troy? I wonder if he even remember self how to colors are supposed to look if he hasnt seen the theatrical copy for years.
The most important stuff for me is that they stay true to the orginal movies look. (How it looked in theaters, not how it looked on video)
It would be fun if we could get some inside knowledge what they did for this release. Its not Warners style to create a new look for a movie without the directors cooperation. That makes me believe that the colors are right but the contrastboost may give it a little to much color.
