Color: a mauve pink, a true-nude color. It works perfectly if you are trying to achieve a very natural-looking lip. I think that it goes very well with mauves, pinks, and browns too, and it would even be a great base for a paler lip. The color reminds me a lot of the Mac lip pencil in Subculture, (with a little bit more mauve), so if you were looking for an alternative to subculture, this might be the deal.
Which lip liner are you using? Let me know in the comments below!
