This image is actually a photo Mike Verta took of a projected technicolor print with a 1970s bulb and screen. It does appear to look a bit off, compared to the actual frame, and the bootleg recording. It might be, that the 1970s bulb emitted a more yellow/orange hue due to its age, or perhaps this is another example of the color imbalances NeverarGreat discussed?
Oh, I see. I thought that frame represented Mr. Verta’s final color grade, as I think yotsuya thought. My mistake!
