Purple is today's color.
I started with two medium coats of NYX Girls Royal Purple, a dark purple polish filled with blue and purple flecks.
Then I added one coat of Darling Diva Polish Ringer, a color shifting topcoat shifting from red to green. I've read that it's supposed to be a dupe to Max Factor Fantasy Fire and the famous Clarins 230, but as I own neither of them, I can't confirm or deny that.
Then I used Kiko polish 622 (Wisteria, Mirror metallics), a blue-ish pastel lilac metallic, and Konad plate m69 for the stamping. I sealed the mani with one coat of Essence Better Than Gel Nails Top Sealer.
Ringer and other Darling Diva Polishes are available on Etsy, at Mei Mei Signatures and at Llarowe.
