Update: The name of this one is apparently Chromance, however mine must be missing the label!
As you can see, it's pretty shimmery and shiny! But it's still not exactly what I would call "holographic," since I usually associate that term with polishes that are very shiny and often have a rainbow effect to them. This one is actually more like a duo chrome or multi chrome.
The main color appears to be purple or blue, but as you turn the bottle, a brighter purple appears along with some hints of coppery orange. It's a bit sparkly, as it also seems to be made up of very tiny multi chrome particles, so it doesn't just give one smooth, multi chrome finish.
It's also a bit sheer on its own, but can be built up with two or three coats. I opted to apply it over Wet n Wild Black Creme though. All of these photos show just one coat of this Claire's holographic Chromance over one coat of Black Creme. Such a simple manicure to achieve, but I think it looks amazing!
As you can see, the colors look different depending on the viewing angle. It mostly looks purple or blue, but the coppery flash you get on the side is an amazing contrast! If Claire's makes any more like this, I'll have to pick them up. This one was only $4!
