Everything's possible I guess, the shooting script describes the green colored opening credits, but that script may be a revised published version just like the various Star Wars scripts out there. The Italian version could've easily used green colored ones to imitate the US original but they are white. Could the video master even fade that much just in 10 years? the opening is easily the part which is in the worst condition on this videomaster, extremely dirty... someone with more expertise will need to chime in on this matter.
