You need Sophie-David’s alien token for this mod to work.

You can add more skintones if you want to.

If alien Sim is also a zombie, they will change back into zombie skintone instead of their genetic skintone. They can also reset their skintone back to their genetic setting. They can change their skintone into Maxis light, Maxis tan, Maxis medium, Maxis dark, mannequin, zombie and alien. This action is selectable on active aliens. I made a mod to let aliens disguise themselves by changing their skintone.
