I feel like the ANH:R graphics were too pretty and clashed with the used universe aesthetic of the film. I wouldn’t mind graphics that are a bit more low-fi but still fixed the dish placement. It would be a shame to break continuity with Rogue One but the blue TIES and red bacta in ESB:R already kind of do.
Okay, so TIEs and Bacta tanks come in different colors. No big deal.
Obviously after the Death Star was destroyed, the empire decided to make their TIEs more intimidating, so they made them all blue. The Bacta tanks took all the red.
