It definitely changes color depending on the warmth of your fingernail and the surrounding temperature. My picture shows the white, as I placed under warm water, the other two were placed in my ice bucket for 5 seconds. This was a three color polish. I've gotten so many compliments! I will note that when applying a gel polish, thin coats are important. My usual gel polish, I need 2 coats, this polish definitely required 3. With 2 coats, I could see the brush strokes. The first coat kinda separated before being cured. The bottles of polish are quite small. Im not sure if I will get two full sets out of each bottle, but I'm hopeful! I haven't used any other colors yet, but i look forward to it. I used a generous amount of no wipe gel top coat as well to prevent any peeling or chipping. If you are looking for a really kool polish, this is it! I'm not a pro nail tech. Definitely recommend. Take some to your pro nail tech as well!
