The trailers raise some questions, because some of them lack any kind of color pushing in the night scenes. I just can't believe that some prints would have no color pushing in the night exteriors, and others would.

And this trailer transfer also seems to be rebalanced for home video?

Speaking of, I noticed that if I just did rudimentary color adjustment on the VCL DVD screenshots in MS Office so that the Carolco logo looks silver instead of yellow, much of the blue blanket comes back.

The Siskel and Ebert review clip has the "you can't go around killing people" scene with a blanket over the scene, but it looks more purple. Though I'm not sure how much of that is due to telecine adjustment, or the fidelity of the off-air VHS recording.
