The colour is fine. Like Adywan showed, it's very easily recoverable using digital tools. The negatives for Star Wars are much more faded than this and you can see how much colour the SE's got. This kind of colour recovery is pretty much standard for most movies from the 1970s. It's the smallest of the problems. The biggest issue will be cleaning up the dirt and print damage, but luckily this print looks like it is in good condition. I for one would like to see the raw scan released, so that we aren't locked into one interpretation of dirt cleanup and colour correction, but maybe that is asking too much right now.
