Isadora Graffiti masterpiece pink nail art

Isadora Graffiti is old news, but I like the pink "masterpiece pink". However in this combination I don't like it that much. Ended up painting black lines with Sure Promise and putted on black opaque star rhinestones on the accent nails. 

Have to confess that I actually don't know what nail polish I used as a base, it seems blue. Or a very thin blue shimmer over a black? Can't remember.
