I’m working on a Starfinder campaign, so explaining all of these and the lore becomes more complex. I’m homebrewing a lot of the lore, because I’d rather make my own than learn a different one (and it lets me make things up on the spot that I don’t know). I know for one planet, its industrial revolution made its inhabitants flee underground, since the surface became too hostile. Magic helps with a lot of explanations too.

which i absolutely believe. when i see dealerships selling oddly colored cars they tend to have a 5k discount. my friend got a equinox that was a but strangely colored for less, and in my area a kona had a 5k discount for being hi-vis green. plus i imagine anyone wanting a specific color would just go to a shop for it.
