There is a bit of a green tint because of the print and/or white balance of the camera. It accounts for some of it, but not nearly all of it. Let's say about 20%.

I should mention though, that correcting the GOUT to look like that, on second thought, is a bit of a futile attempt. In all likelihood it would make it look worse. The reason being, there is so little color in the GOUT that when you pull it out you get all sorts of noise and colour patches and it looks kind of gross, it would probably be popping all over the place too. Even the milder saturation boosts on all the Avisynth projects had some colour popping issues, and also bleeding in the reds in some instances. I tried experimenting myself using the GOUT in photoshop to match the Technicolor levels but it just isn't the same, and video colour correction isn't as good as photoshop. If you were working from a film scan it would be different, but the GOUT is just really crappy 20 year old video and it can't withstand that much manipulation, at least from my own attempts. Personally I think leaving it as it is, or going with the milder saturation boost of previous attempts, is the best it can look colour-wise. You could maybe brighten the sunset scene and get rid of the blue, but I don't know if the noise would be too much.
