Honestly its going to get very messy from this point on, over at the 4K77 forums there are half a dozen people doing their own color grade, several versions all at varying stages of restoration.
I think projects should either stick to original unaltered colors or go all out and do a proper shot by shot grade for consistency and balance and to make it what a real back to negative restoration would be. I like the latest release, but It could be a lot better.
