Admittedly, I feel a little foolish not noticing the button color detail earlier. It's one thing to miss it as a kid, but I missed this detail two or more times after that. Even though Kenobi's plea to "use the Force" proceeds it, I still failed to see it. You're smart for having noticed it. Thanks for the comment.
It could - thank you for a solid counterpoint. There's no certainty when talking about symbolism unless the filmmaker confesses it directly. To me, it seems that manual control being "on" corresponds better to red than the green - but that's just a hunch, based on my expectation/bias. There are also accidents (even in planned scenes) that retroactively appear as intentional, just because of how they happen to land, or due to some detail a director wasn't even thinking about. I don't think that's the case here, but it's always smart to consider it as a possibility, and I'm glad that you brought it up. Growth comes from considering alternatives - which is a tendency I'd like to hold onto, despite my interest in the symbolic.
