It's probably not really the right time to show you a polish called Indian Summer, but well, it's pretty, so that's a good reason to show it out of season, right?
Indian Summer by CrowsToes is a multichrome shifting from blue over purple to a pink-ish red. I used three coats for opacity (no black base needed).
For the stamping I used Lily Anna plate 05 and Barry M. Lilac Foil, then I added one coat of KBShimmer Clearly On Top.
Crows Toes polishes are available at their own store (US only), Femme Fatale Cosmetics, Color4Nails.
