This photo is what it looks like most of the time on me. It is the "warm mode" of this polish and is heated by your body temperature. You can see it's a nice pink and it has a bit of flecky shimmer.
This is the polish's "cold mode." For this photograph, I dunked my nails in ice water (you can see some of it on my fingers, hah). It will also change when you wash your hands in cool water, or if you have cold hands. It becomes a very dark purple color. You can see my thumb is retaining it's warm pink color because I didn't dunk that nail.
If you have warm hands but just washed your hands in cool water, for example, as the water begins to dry up, your hands begin to heat the polish again. It creates this cool gradient effect and you can watch it changing right before your very eyes!
Another thing this polish will do sometimes is just change colors on the tips, where the nail is not attached to your finger and therefore not heated as constantly. I found that the polish didn't do this for me very often though, and would only really consistently do it if my hand was in front of an air conditioning vent (like in my car). However, this could be because I'm in a desert, and the surrounding air isn't colder than my body temperature...
To best demonstrate this polish's effect, I've taken a video! It starts with the polish at normal temperature, and then I dunk it into ice water. As you watch the video, you can see my fingers starting to warm the manicure back up and it changes back. Any place that water is sitting on top of my nails stays purple because the water is keeping those spots cold!
