It takes some getting used to, but this print is seen as being in pristine shape. It was screened at the now closed Senator Theatre a number of years back. Here are more photos from this screening:

In any case, I was simply trying to match the print. Whether the print has the correct colors is a matter for debate, but I think it would be a bit presumptuous to call them totally wrong, as it is one of the few prints from that era that has survived in good shape. Technicolor prints are known for their saturated colors, and their ability to retain their colors virtually unchanged for decades.
