Buy some samples from E-bay or the lovely gals here to try them out. My suggestions would be
Coco (le)
Goldenaire (le)
Gold Dusk (le)
my very fave (I am NW15/20)
Vanilla
Then depending on your eye colour
Blue eyes : Chocolate Brown or Coco Beach, Violet
Hazel eyes: Coco Beach, Teal, Nightlight, Deep purple, Ruby Red
Brown eyes: Pretty much anything goes, but blues, pinks and greens look great imho.
Green eyes: Chocolate brown, Old Gold, Ruby Red
