I think the filter on the Launch Trailer is there to show what happens during foggy weather.
We have already seen that when Jason or Lucia wear some eyewear, we get an effect on the screen. I know there were some scenes that were during different weather, but they put it on the entire training for some symbolism or something? Maybe to say that we are entering a foggy time with how release is coming so soon. Something along those lines. What do you guys think?
