Copied from the Color Stories thread...
Light O (Asia Only): C25, NC15, NC20
Light: NW15, NC20, NW25
Medium: NW20, NC30, NW30
Dark: NC35, NW40, NC45
Deep Dark: NW45, NC50, W55
I use both NC15 and NC20 and also a lighter color from Jane Iredale for mixing... so the Light O palette would be perfect for me :/
