I have three of the Prismatics for you today, first up is Full Spectrum.
Liquid Crystal is one I split up to two photos for you. On my middle finger I did two coats of and on my ring finger I did one coat. I like one coat more because you can see the shimmer in it more. I wouldn't call these duochrome polishes. Liquid Crystal has a really great pink shimmer to it in a light blueish base. When you do one coat, you see much much more shimmer but once you add that second coat, it goes away and you get more blue.
Overall these three are super glittery and sparkly and I think I'd prefer them as single coat with a color underneath so that the shimmers are showcased more. These are available now, so keep an eye out!
