Is having one-color body skin tones allowed in in-game customization against the TOS?

Hey, so I’m making a retro styled game where you’ll be able to select certain body parts and color them out of all the basic colors. Among these colors are skin tones.

Do I have to code in any sort of way of stopping whole body colors (e.g. making the legs black or forcing clothes) or is this allowed outside of the official avatar creator? And is it only for human skin tones or does it apply to any color as long as it’s the whole body?

I would personally consider it fine just because of this. The intent of the game is pretty clear.

I’m not sure if it’s allowed for all skin tones, but definitely ones that are not considered humanlike.
