In no particular order, a list of my personal favourite skintones (( +ramps! )) in the Sims 3 and currently in my game now. Don't be like me and download every single skintone you've ever seen in your life and add them ALL into your game. I did that.... ONCE.

* There are many, many, MANY more skintones I've downloaded and use in-game that I randomly find on CC Finds blogs, so this isn't considered a completed list by any means. I have quite a lot of tattooed/vitiligo/freckled skintones, for instance--and some I made for my own Sims (( aka, characters )).
