It's some yellow-depends on if it's really a 73, or a 71 like they now say it is-it looks like a mustardy yellow in the movie, don't know if it's just an effect of the old tapes or not though. There is a really nice deeper blue for the big bodies-our replacement pass quarter is a very faded version of it, I like it. Ours is originally yellow (what's left that original anyway!!).
As a direct result of this thread, I have found a genuine VHS copy from, I guess, the early eighties. It's a UK PAL version, so I have no idea what to expect, but I'm looking forward to it when it arrives.
I think, that it will make me end up with the US NTSC VHS version, and also the re-mastered DVD...
