Hey, y'all... I had similar issues with the fingernails and toenails situation not showing or not being able to be changed too. In local, type the following to show and hide your fingernails and toenails, then change the color in the style (2nd) button to change the color. I mean... Afterall, if we love that our partners take measures to look their best for us, we can copy/paste and make an effort for them too, right? ENJOY!
