Firstly, what I did and with what products. The base color is Pure Ice Saddle Me Up. I used scotch tape to create the diagonal sections. The teal is Funky Fingers Partly Cloudy (That's the color changing one!) and the black is Sally Hansen Black Out.

I was a little bummed that the top coat made the color not darken as much. Fret not! I went back out a while later and, as it turns out, the top coat merely causes the color changing process to take a bit longer. An extra 15 seconds and it was just as dark as the shot without topcoat. Phew!
The formula on this polish is the usual Funky Fingers formula. It's a bit streaky and uneven in one coat, but fantastic in two. I'm very happy with this purchase and I can't wait until the next sunny day so I can play with my other color changing polish! The best part? It's only $3! Go out and get one! Now! :)
