Heartbreaker is a bright red glitter that is supposed to turn purple in the sun. Red glitter polishes always remind me of the winter holidays, and since it's spring I wanted to see if I could use Heartbreaker on top of something else (like I did with Ruby Slippers) to mix up the effect. The pic below is Heartbreaker (without sun) on top of silver, black, and white:
There wasn't much of a difference between Heartbreaker on its own (first nail) and Heartbreaker over white (last nail). I had hoped it would look more pink over white, but the red jelly base turned out to be fairly pigmented so this was a bit of a failed experiment.
Now, the same combinations in the sun:
As with Girls Night Out which I posted about in January, the color doesn't transform into a true purple as the label would indicate. It becomes more of a fuchsia color, slightly darker than the outdoor version of Girls Night Out. I like the fuchsia but I'm not as thrilled about the red indoor color, so I probably won't use this again for a manicure. Maybe it would be perfect for a pedi?
