My favorite: “I’m the sweet minister’s daughter, and you’re just yellow trash.”
I wasn’t seeking a rationalization, simply wondering if there was more to it than I suspected. I stated this in the OP. What if there was some perfect explanation and I went about my day not knowing it? That would mean I was ignorant of the fact that some Simpson’s characters have blue hair for a reason. I don’t want to be ignorant, not even when it comes to something so trivial. In other words, it was just a question.
Homer (From the episode in which his father dates Mrs. Bouvier): “If he marries your mother, Marge, we’ll be brother and sister! And our kids, they’ll be horrible freaks with pink skin, no overbites, and five fingers on each hand!”
…oh, and my own idea…blue hair in Springfield is about as common as red hair in RL…
First rule in anime: Beware of the new kid with blue hair. Maybe they hail from Springfield.

Quoth Walloon:
In support of this, am I the only one who remembers that Superman used to have blue hair? Same reason there, I think.
Hey, sometimes a guy just wants his skin to look its yellowest.
moe had black hair

If you have regulars like Homer and Barney, you tend to get grey fast…
My theory: blue is a natural hair color in their world, but quite rare. And that’s why Marge is aghast at the idea that she colors her hair–even though she does.
I’ve noticed a lot of drawn characters have orange hair.
Like Fry! Like Fry!
Oh wait, wrong show.
Futurama DID have a crossover with the Simpsons. https://en.wikipedia.org/wiki/Simpsorama
Maybe the blue hair and yellow skin is a precursor to the Mutants on Futurama.
