So who seems to have nail the right color for a new hope that doesn’t conflicted other colors in the film like in tantave scene the inside of the ship getting the right colors without messing with the storm troopers color vader’s color and c3po’s and r2 d2’s color etc. this or Neverar?
As far as I know, it is the goal of no one to produce some sort of color continuity saga. The goal is to get them looking like they’re supposed to, not to make them match. There is no reason to do that. Films are graded and not necessarily in life-like or consistent ways. Colors across different films do not “conflict” with one another. R2 is a different color in different films because R2 is literally a different color.
Honestly, if you want consistent grading the best bet is probably to just grab the 2011 blu-rays which have a very similar terrible blue cast on 4 of the 6 films. No one here has ever expressed interest in such a thing, as far as I know. And if they did, they would never dream of trying to get them to match the prequels.
