Godzilla 2000, the last theatrically released Japanese film in the series is no stranger to bizarre revisionism. When it was brought to DVD, per Toho's request, the cheesy THE ? END title was deleted, but the color seems to have also been changed significantly. The U.S. theatrical version (or something much closer to it) is available on the screener and Spanish subtitled tapes. Note that the Japanese version has always looked pretty different on its own, but the "theatrical" coloring is closer to it.

Some examples:

U.S. theatrical version

DVD. A lot of the composites suffer from the new grading.

So much of the greens are missing from this version. Oddly, the DVD removes a lot of the blue and orange contrast displayed in a lot of scenes.

Blu-Ray. A lot of the greens are back in full force, but at the same time, some very questionable coloring changes have been made, particularly in the reds and oranges.

U.S. HDTV/Streaming version

Blu-Ray

Then you have completely oddball, nonsensical alterations, like this particularly infamous CGI shot:

Godzilla IS comprised of green and dark purple in this movie, but Jesus Christ, he looks like Barney on the Blu-Ray...

A few more restored greens on the Blu-Ray, such as this shot.

Bottom line, the Blu-Ray improves on some things the DVD screwed up, while introducing a host of new problems. The HDTV version is the way to go I guess.
