Peculiar Patina is a multichrome flakie polish that shifts from a bright pink to copper to yellow to green and blue on the very far end. Looking closely you can see a smattering of multicolored Ultrachrome flakies. It's an UltraDENSE version of the Ultrachrome flakie polishes making rounds in the polish world. You can see from the swatches that it's beautiful in one coat but you can get full coverage in 2 coats!
If you're unfamiliar with the qualities of these flakies here's a rundown. They are unlike the glass shifting flakies which are clear, these flakies are opaque so you can wear them on their own. Meaning there is no need to wear over a complimenting color or dark polish if you don't want to but they look great that way too! They are also unlike glitter in that they come off very easily. No rubbing or soaking needed, they come off with remover just like a typical polish without glitter would.
In the second pic you can see two coats over black on all fingers but the ring finger which is two coats alone.
