I needed a purple with a blue/aqua shift so I made one with pigment and tkb's crappy base
and I made a layering shifty shimmer thing color too which I used just on my ring fingers
Love, love, love the color but the base is such a mess that it was really hard to get even coverage
See the pretty shift
On my ring finger you can see the pink and aqua shimmer
Not loving the ring finger but the rest is a happy color
I might start carrying some franken pigments on my site for those who want to play without the extreme error factor. Still thinking about it.
