Plumeria is a pink holographic thermal. It shifts from a very light baby pink, almost a clear silvery colour when warm, to a bright berry pink when cold. You can see how it transitions in the photos below. This is 3 coats on it's own.
Fluorescein is a neon green jelly packed with scattered holo that glows under UV light. It's a little on the sheer side, the pictures are 2 coats and there is still vnl. You would probably need 3 coats or to wear undies for full coverage.
You can purchase Polished by KPT directly from Katherine's Big Cartel website, (US & Canada shipping) but they are now also available at Shoppe Eclectic and Harlow & Co. In addition to polish, Katherine also sells beautiful polish jewellery.
