Having looked at the 1997 reference williarob shared in the past in some detail, it is clear, that the colorist clearly used the 1997 SE as a color reference for the OT. It’s also pretty obvious, that the 1997 SE prints are not as vibrant as for example a technicolor print.
Still better than the 2004/2011 coloring. I watched parts of the 4K77 and 4K83 restorations and the 2019 restoration look very similar (minus 97 additions & recuts).
