im not good at spotting the whole teal/orange thing but this trailer it looks like the overall color is slightly dialed back. I think the nighttime forest scene in the teaser was fine, and we dont know if the blue light with the stormtroopers was because it just had interior light thats blue.

walking_carpet, I just happened to comment on this over on Fanedit.org in response to emanswfan's recolouration of the teaser, but I'll repeat it here also -

The other day I actually paused the teaser at the very last moment of the shot showing the back of the legs of the new Stormtroopers as they are about to disembark down the ramp - the reason?...I was curious to see if it was possible to get a glimpse in that shot of what their 'footwear' looked like in any way, as it changed considerably between the Original Trilogy versions and the Prequel versions (or the other way round to be technically correct). No luck however, as the shot just cuts off as it pans down the back of their legs towards their heels.

However, while I originally thought those Stormtrooper shots had been given a distinctly blueish/teal colour-grading overall, it actually turns out that it indeed seems that it's just the colour of the lighting inside the transport they're waiting in that is reflecting the hue on their armour...as the precise moment I paused the end of the shot shows the legs of the Stormtroopers turning to gleaming white after all at that point, as the ramp door opens wider. It's just that the shot ends abruptly at this point, too quickly for our eyes to catch this last frame. So I'm satisfied that the blueish/teal look of those particular shots is just due to the colour of the lighting reflecting off their armour after all, rather than due to deliberate colour-meddling.

I'm pretty pleased with the teaser overall, and I'll go into more detail why later on today sometime.
