COLOR WHEEL!!!

I can deal with B/B color choices and the clothing ones but the hair and skin colors are truly starting to make me crazy. I've been playing way over 1k hrs and because of the lack of options (especially with hair colors) my sims look way too heterogenous in all my worlds.
I basically only use the natural colors: black, browns, the natural(ler? Haha ?) red and the natural blonde. And for some reason it seems I unintentionally go for the red _a lot_.
If not a color wheel, could we at least get some additions to the natural skin tones and hair? Pretty please?
