Don't get too excited about this old transfer.

A lot of 80s/early 90s transfers looked very "neutralized", probably in order to read better on CRTs - for example, in early transfers of Empire, Hoth looked very white (more white than any extant print sources we've seen), and Yoda (and Dagobah in general) looked almost gray.

I'm wondering if this transfer also had a yellow boost so that the image would "read" better - the Carolco logo looks almost sepia-tone.

Not trying to pooh-pooh it - just saying that the Siskel and Ebert clips, which were during the theatrical release and thus clearly not timed for home video, have a much more pronounced blue cast in the night shots than that old DVD (possibly originally LD) transfer.
