This past year I have added ten polishes in to this category;
Cirque Colors Last Unicorn // Orly Ceci N'est Pas Blanc // Orly Dreamers Awake // Orly Unravelling Story // Orly Endless Night // ILNP Orbit // I Scream Nails Holo Be Thy Name // Orly Shaky Alibi // Barry M Cinnamon // Orly Act of Folly
After thinking about it the following were my top three;
In third place is Endless Night, a gunmetal grey metallic which leans slightly blue.
Picking between the top two was difficult, however Orbit won because I own quite a few black holographic polishes and Orbit is unique. It is a grey to red ultra multichrome polish, similar to ILNP Eclipse but grey rather than black.
