i understand your line of thought...actually i just thought of something. If im not mistaken in the official dvds didnt lucas make the explosions that take place in space black and white? or at least fade the color down considerably? if thats correct, maybe the faces restored them to their proper brightness and then he decided to 'tone down' the color of the lasers in the se's just like he did with the explosions in the dvd release.
just a thought and one that may be based on misinformation to begin with (the black and white explosions)

ps. doc, i hope your kidding about the added scenes being the good part of the se's. didnt see a and text doesnt hold sarcasm well. but those are the parts that change the story
