We are not actually using the laserdiscs as references, but just presenting them for comparison.
There are quite a few threads about the colors on the laserdiscs, so asking there, would be a better idea.
Some of the shots do match up pretty well at times, and others do not. It varies with the laserdisc versions, and when they were released.
We will be doing an extensive color correction when the time comes.
