Which purples have you used? I'm also Asian NC30. I've used purples and my eyes have popped .. *lol* that sounds funny. Anyhoo, the more violet the purples the better, I find. Trax, which is more burgundy, I have to be very careful in using. I actually rarely touch it. Oh, and I almost always use Violet Underground eyekohl, sometimes Non-Conformist fluidline as well.
Here are the shades I've used successfully:
Violet p/m
Lovely Lily p/m
Satellite Dreams e/s
Entremauve p/m
Leap e/s (from the Danse/Corps de Couleur quad)
Mancatcher e/s
Thunder e/s (from 2006 Icon Thunder quad)
Jeweltone e/s
HTH!
