I must repeat, Lowry had nothing to do with the colours. In another thread somewhere I have posted links to articles from Apple's and StarWars' official site where it is clearly stated all the colour work and effects, etc were done by LucasFilm, Lowry simply cleaned the film to make it practically free of dust, scratches, etc.
links? I'd be interested in readin that actually. the whole DVD process articles would make an interesting read. if it wasn't lowry then lucasfilm are even more guilty for rushing this thing out than I thought.
