Pink or red doesn’t really matter. They’re engines, the colors don’t mean anything.

The Death Star graphics though is something I’m worried about. It was a simple mistake in the original. Rogue One using the same graphics was their way of fixing the mistake - same as adywan in ANHR - by making it seem like it was intentional. But it still makes little sense, and requires a bullshit explanation outside of the film to explain why it’s that way (the hard drive has every version of the plans I guess?). Even with that silly explanation, it doesn’t make any sense at all for the Rebels to be using and showing out of date plans when they’re planning their attack. I think you can still keep continuity with RO and still fix the plans (in RO we see early versions of the plans and in ANH we see the current plans). To use the old graphics for the briefing scene is a huge misstep, I think.
