That's not paranoid! That's a fantastic thing to do and one that I highly recommend for anyone. It's terribly easy to forget which environment you're working in when you get distracted for a moment and that's how mistakes happen.
I liked the green / white text theme the most with blue being my second favorite to write code in so those got the ones I would use the most. I was never a lover of the old amber terminals and red is just plain painful to write on. I guess the more pain your terminal causes you, the more dangerous the environment.
It's hideous, of course. But it works very well for me, and I don't suppose I'd be averse, if interest becomes evident, to sharing it somewhere for others to benefit from and/or peruse in horrified fascination.

Outside GNU coreutils, the only dependencies are mysql(1) (of course) and jq(1), which is more or less "awk for JSON" and which I strongly recommend to anyone who regularly deals with that file format.
Share and Enjoy!
