doubleofive said:I don't remember where it was mentioned, but there's an article the specifically states that ILM did the colors and just had Lowry clean it. I think ILM tried to restore it themselves to save money, messed up the colors and hoped Lowry could fix it.

That article mentions that Lucasfilm scanned the negatives, carried out the "re-mastering" (I assume this means the '04 alterations) and the re-colour timing. Then then attempted a cleaning pass through ILM, before deciding to give the job to Lowry.
Lowry received high-definition scans to work with from Lucasfilm. Although it is not clear in the article, it's reasonable to assume that the scans provided contained the tweaks and the new colours.
