Yet again, I must bring up the fact that the low fade 35mm print of Raiders that turned up on eBay a while ago clearly showed a color timing that was very similar to the Bluray.
This film has always been gold-tinted. Always. The Bluray transfer is an attempt to recreate the original color timing, though since it was done digitally and not photochemically, it may not have always turned out exactly the same. But it's in the ballpark, and its intentions were in the right place.
What you see on these other transfers is more akin to what was shot on the negative, before the initial color timing for interpositive would have taken place. It also does not take into account that projection bulbs from that era were much warmer in tone than they are today. The wowow transfer may be an accurate representation of what was actually photographed, but it does not represent how the film would have looked in theatres when it first came out.
This whole controversy reminds me of the time before Technicolor print references became available for Star Wars, and we didn't know what that film actually looked like originally. Everybody thought the grey appearance of the Death Star on earlier home video releases was how it should have been, only to be disproved when it turned out the Death Star was actually quite blue in a lot of shots all along. If the pictures from the eBay auction were to be posted here, the Bluray's undeniable resemblance to the film print could be seen by everyone. I really wish now that I had saved them . . .
