Last saturday I bought something from the new collection of Essence:
Colour Arts
you can mix and match your own eyeshadow, lipstick and nail polish
you only need a eye base, lip base or nail base and
pigments, which are available in different colors.
I bought Broadway Starlet 04
I think the photo failed because in real life it looks much better
although I really like it
What I've used:
Essence - Make a Wish nail polish
Essence - Broadway Starlet 04 pigments
Catrice - Quick Dry & High Shine top coat
You start with dropping some pigments on a paper
You mix those pigments with a base/top coat
make sure it doesn't matter that there are pigments through your nail polish
After you mixed the pigments with the nail polish
you lacquer your nail equally
Actually it is really simple (:
Good Luck
