I'm so happy with my newest nail art.
The top layer is a temperature-sensitive color changing gel that's purple when my fingers are cold and red when they're warm, with a bit of glitter for good measure. Below that is two layers of white cat-eye or magnetic nail polish, oriented in cross directions, so there's a shimmer that depends on what angle you look at it, with some depth. There's one more layer on the bottom of a translucent red jelly to add depth and subtly enhance the top colors.
For this photo, I washed one hand in hot water and the other in cold water to show off the effect.
Between the changing colors and the cat-eye effect, these nails look different every time I look at them, and I love it.
