This one still works for me. Like I said, I'm pretty sure these are colours optimized for anaglyph 3D presentation - when this is done, red and cyan tones are pulled out to avoid the glowing colour effect when using the anaglyph glasses, which is exactly the case here - yellow (eg. skin tones) and orange (eg. Maul) tones instead of red tones and purple tones (eg. Obi's lightsabre) instead of cyan. It seems that they intended to release a 3D anaglyph version and then just used the left of right eye footage for the 2D trailer forgetting about the colours. And when they realized this error, they corrected it.
