This is a difficult subject to discuss in a community with many bad-faith actors, but...When the big major skintone update came out, the pale skintones that came with it were and remain terrible. The look sickly. They look purple and blue. They are by and large unnatural looking. I do think we traded one problem for another- a lack of dark skintones became a lack of (usable) lighter skintones, and because of the context of the conversation, nobody really wanted to have it. I think enough time has passed to admit the bulk of the lighter skintones in Sims 4 are not good.
There aren't that many pale-to-light-tan skintones that are actually usable IMO. At this point, we truly do simply need a second skintone overhaul to fully color-wheel and tone-adjust skintones.
That said, several parts of this post feel...weird. Like expecting all the townies to have "English" names. Some of those townies are Japanese, some are Indigenous American, some are Irish- they aren't going to all be English names. Now, are there bugs where too many Sims are Japanese and has that been an issue for years...? Yes.
