i have really pigmented lips too. you can always use concealor and block out your natural color, nude them out that is, and then work from there to acheive the color you want. i either do that, or i use really pale, pigmented lipsticks [myth l/s, freshbrew l/s, 15minutes, etc]. i use those pale l/s to block out lighten my lips.. then work from there. if i dont want nude lips, but still a shade lighter than my natural, i'll wear a l/s over the nude out l/s to build the color up.
