The blu-ray IS the original color timing, it was just someone happened to grade the print scan floating around the internet to match the DVDs.
According to a friend of mine who saw a recent screening of an original 35mm print, the yellow tint of the blu-ray is supposed to be there, meaning the version floating around the internet that’s of a print has incorrect colors like the DVD.
Don’t believe what others say cause they’re most likely basing their source off of the incorrectly graded print circulating around here.
