If you were hoping to have some pink, purple, or orange Sims, you’ll be happy to know that The Simsperience has released 95 different skin color overlays for both adults and children. Details here.
These are the 95 different skin tones on just 1 of the Sims 4 Skin Colors! I put a red square around the skin tone I used in the picture below. That means there are an additional 17 skin colors available for you to put these skin color overlays on! Overall that is 1710 different skin shades!
