So, I was thinking; there are many small colour anomalies in the original colour timing, like one shot having a blue cast and the next having a purple one and such. Most of the time kept true to them but I did make one rather major exception: the two shots from this angle:

The top is how it appears in the WP, the bottom is almost exactly how it appears on the I.B. print; all the other shots in the print look pretty much the way they look in the WP, so these two stand out quite a bit. What do you guys think, should I make them look like this?

Top one!

I can't imagine this was anything else but an error. Is the IB print really an indication about what a pristine theatrical copy looked back then? Either way, the miscoloring wasn't a result of a technical limitation, budget constraints or lack of production time... someone just made a mistake after the film was finished.
