I've decided to only wear polishes from my untried pile from now and and Ozotic 531 is the first. A holographic, multichromatic beauty, this polish is both subtle and outrageous at the same time. While I predominantly see a muted salmon colour like this on me, 531 also shifts to bronze, pink and lilac. Oh ~ note that I used Essie Demure Vixen, a light pink colour, under 531 and not black. I suppose the results would be brighter under a black polish, but I like it just fine like this.
