Considering the subjective nature of human vision, not to mention the variation in print tone, I don’t think anyone would have noticed a bulb tint in the theater. I also don’t think it would have changed the tint of the color so much. I still vividly remember watching the 70 mm 5 Star Trek marathon in Denver. Some of the reel changes were painfully obvious because the film would change tint and be more red or yellow than the last one. But the eye quickly adjusted and I forgot until the next obvious reel change. My understanding of how film print sets were assembled indicates this was normal print variation (with the copy I saw being assembled from the best available prints after the original run). They normally tried to match the tone on new film so audiences don’t notice. This was particularly difficult for Pleasantville.
So while I admire your dedication to choices you feel add to the 70’s feel, I don’t agree with the end result.
Most of what I was trying to say initially was that when we perceive a color issue, we tend to over correct. I feel the yellowish tones are an over correction. I don’t think it matches the majority of films have seen. You have a different perspective. That is fine. That is why I’m doing my own color correction. My opinion (on several things) seems to be in a minority around here.
