Maxis has currently locked the sliders 'where it did not provide an optimal experience or make sense for the makeup,' but is working to improve these issues in future.
Sliders are now also available when applying a sim's makeup, which means players can alter hue, saturation, brightness and opacity. Skin tones are now filterable to warm, cool, and neutral tones - along with miscellaneous to cover occult skin tones like blue and green. Today's free update adds over 100 new skin tones to the character creator, along with a customisation slider to change the light to dark value of a skin tone.
In response, executive producer Lyndsay Pearson acknowledged the team needed to do more to include a variety of skin tones and hairstyles in the game: and an update to help with that has now arrived. Many pointed out that the darker skin tones lacked vibrancy and looked ashy - while makeup often appeared patchy on some of these tones. Earlier this year, Sims 4 players asked Maxis to improve the skin tones available in the game.
