AFAIK, IIRC, all the releases of Snow White are not accurate to the original colors. The 1993 restored LD (first release) was somewhat mildly criticized by an old animator for having colors different than the ones they used (albeit nice alternative colors). The DVD and the BD are pretty similar. I've always wanted to find out how Snow White looked originally but the only hope may be a 16mm/35mm print transfer pre-restoration or a VHS recording from the 1980s, which probably would have faded anyway.

I may have something of interest to you. An infamous (at least between italian collectors) pirate vhs from 1991 that is apparently sourced from a 35 mm telecine, possibly from the 1980 re-release. The colors don't seem to match the dvds. It even has, though visibly inserted and in a different aspect ratio because they were from the Widescreen 1972 re-release, the original animation for the italian text that Disney animated in 1938.

Now, I should have two copies of this, both in the garage. Gotta dig them up some time...

EDIT: there used to be a couple of videos of it on youtube, but they've been taken down
