I like using it a couple of ways:
Nanogold as highlight
Paradisco on lid
Contrast (or other dark purple/ blue) in crease and outer V
(works great with a purplish plum lip colour like Desire, applied lightly)
Crystal Avalanche or Vellum as highlight and on inner part of lid
Paradisco on outer third of lid
Black liner, fairly bold and winged at the sides
(works with a strong red lip like Russian Red, MAC Red or, for a more subtle effect, Mystic)
