Indoors, weak sun, sun, shade. Nice formula, you can tell because I did such a neat job, and it came out ESPECIALLY well on my right, which is normally a smidge lamer because of my nondominant hand. The bottle duochromes a bit, but it's hard to get it to show on the nail, and this I don't really have pics of that. Sorry! Anyway, jeez, I should change the name of this blog to purple-aholic.
