Here are the purple glitters I have. You can see that some of them are transparent/color shifting. This means that you will see different colors when light hits it or background color changes.
Jelly, Passion, and Barney are pearl/matte glitters.
Darlin' Nikki, Ducking Gorgeous, Tinker Bell, Millennial, St. Charles, Primetime Shards and Primetime are all color shifting glitters.
