Yesterday, I spotted a display with five new Maybelline Color Show polishes – called the Holographic collection (now available online). Unfortunately, it turns out that they aren’t holo – or even meant to be holo! There is a description of the collection on Maybelline Canada’s website, and it says that they “shift from shade to shade depending on the angle” – that is, they’re meant to be duochrome (they are not very strong duochromes, though). If you’re not familiar with the difference between holo and duochrome polishes, Nihrida has a guide to nail polish finishes.
However, as disappointing as this collection is, I still have information about all the shades & swatches of two of them.
