Thanks for the capture clarifications.

... if theres a way to undo the red-infused colour mix of the widescreen versions, back to less uncontaminated colours like on the 82 laserdisc. ... (if red shift is the result of missing blue and green information- can this be added/painted back in using an earlier source to gauge the right levels?)

GOUT '82 LD 70mm

I can't say any of these "graded" versions strikes me as being "right", but, if you wanted less "red" in GOUT, for example, adjust the red channel gamma downward (I used 0.8 to emphasize the effect):

If, instead, you had added more "green" & "blue" (gamma upward), you'd get the same color result but with a lightened picture.

If you like the '82 LD color in the GOUT, that is an easy adjustment, too -- a decrease in the red gamma and a greater decrease in the blue:

This way, you should be able to regrade the entire movie to your liking with a minimum of effort.
