That's fair. I would probably leave off the last part in the question about color perception difference and say instead:

"Why would Uhura and Spock disagree on this?"

I could definitely test run the questions a bit before using them again.

They worked a year and a half ago when I first made them. But LLMs are getting better.

I will Tweak them to make sure they are more fool proof.

I still think it's a reasonable approach. But it does need testing.
