You can't really use the grading done for a trailer to indicate what the final film will look like. Those two new pics taken on what looks to be a camera phone off a projected screen, well by all accounts those are from the full trailer which is being finalised right now to be shown at comic con. The trailers were most likely handed off to a different department, not actually working closely or at all on the film. Ryan's link to the video proves just how different a trailer can look form the finished film.

In your blog, you use pictures taken from the GOUT ESB to prove your point. Well it's known just how inaccurate the original colouring is represented with that release. It's cyan layer had already started to fade off the print the source was taken from. You can tell that it has already red shifted. A hell of a lot of blues are gone.

You mention how orange Boyega's armour is in that one shot. It comes right after the shot of the TIE blowing up the hangar. It was either graded like that so it follows on and looks to be part of that shot, or it is in fact part of that scene and the orange is lighting from the fire in the hangar. No one knows right now until we actually see the film and see these clips in their context. Maybe it's best to wait until the film is out first?
