I have Irridescently (I don't feel like running downstairs to check the name), which is a pinky toned one (I'm assuming the "cool down" one?). Anyway, it'll sometimes change the tone of my color TREMENDOUSLY... for example, over Rage l/s, it'll be a strong blue toned hot pink!! I've also worn them by itself and it's not sticky. I got it off ebay and I haven't regretted it!!
