So I don't know if it helps, but I've got three different versions of varying quality. The one I just purchased is lacking most color, there is a handheld camera version I downloaded from YouTube (Harmy's suggestion) that has great color but is very shaky, and I downloaded a copy by a fellow named Martin Smith which is better color than the yellow version, but still not a whole lot of color. It looks like it was probably a handheld camera version that was edited frame by frame to only include the screen and is thus not shaky, but it shows a standard camera shot from the audience in a couple of points as filler when apparently the better source didn't work out. I don't know if somehow using all three version could help an ambitious person to recreate something closer to the original or not. I imagine it would be a very interesting preservation project, but I don't know if someone talented is interested in the idea enough to devoted the time to it.
