(There were several trailers before it, which all had a similar yellow-green cast, though still a broader color spectrum).
I would guess that the projector was projecting with a yellow-green cast, and this was the primary reason the film looked as it did. But while it might not have had a yellow-green cast, the fact that it had a reduced color spectrum compared to the trailers may indicate the it looked different in theaters then on home media.
