Just regular color. My mother wasn't the only monster in my life. My exes assumed that if I was painting my nails, taking care of my hair, wearing colorful clothing, or used perfumes or even scented soaps, that I was "inviting" other men with my appearance, so how dare I attempt to cheat on them. :|
I started working for my own when I was 15, full time at 17. I would have gotten my own place if my mother wasn't stealing my money with "rent" and "utility bills" for living at home, even when I was still in highschool. Most of the time, I wouldn't even go home for days on end. I made friends with bikers that would trek me all over the place, other guys that liked to offroad and camp out for days-on-end, stoner friends that I could chill with for extended periods of time, and nerds that built computers and arcades for days-on-end for fun that I'd hang out with, along with other (more normal) friends that didn't mind me hanging out for a while. if I was alone, I'd climb trees, buildings, towers, mountains, and just watch the sky for hours to pass time... That was essentially me when I was young.
My husband was angry with her, but he is also very smart... somehow he managed to get me and my sister talking outside of heavy hostility, I still don't trust her at all, but I talk to her again... He also managed to convince my mother to let me have a single painting from the house before she auctioned all of my grandmother's things. He did the same with several my exes, now they're no longer spiteful (or at least spiteful enough to openly attack me or my kids). I've come to trust him implicitly as he essentially gave me a life, in almost a literal sense with how free I am now.
That said, I barely ever did anything with my nails beside color, but now I do all sorts of things like bead them and gloss them and all sorts of fun stuff that I missed out on for so long.
