Nicole by OPI- Enchantress

This is a color from the core Nicole collection, not a Modern Family or Selena Gomez color. Nicole by OPI runs about $7 USD per bottle, and is available at drugstores, beauty stores, and mass retailers like T.J. Maxx. The color is a sheer pink duochrome, with flashes of blue and purple depending on the light.
As pretty as the color looks in the bottle, you are going to spend several fruitless hours painting tons of coats on your nail and waiting for that to dry. To get a more satisfactory result, I would recommend putting down a coat of white and two thin coats of Enchantress. I bet it would look really cool over black, too!
Excuse the messiness of the pictures below. My white polish was really acting up and got everywhere it was not supposed to go. You can't see it in the pictures, but the white polish also bubbled a lot. Enchantress is the high quality polish here, so get an equally high quality black or white base to match.
