So, have a set of color correction values been come up with for each movie that will correct the 2006 Star Wars trilogy DVD's about as close as one can get to the original theatrical colors within the limits of that DVD source? After all the adjusting and fine tuning, wondering if there is some agreement among the experts here on what provides the best overall correction?

Check out You_Too's work with DJ.

His color-correction (primarily GIMP curves files loaded into Avisynth via GiCoCu) is probably the most accurate we can get with the GOUT DVDs.
