I used 1 coat of Essie Ole Caliente for the base, and as you can see, SHXW Sun Kissed is the other color. In retrospect, I should have sponged the orange onto the tips rather than the base, because I can see a few spots around my eponychia where Ole Caliente is still visible...I also had issues with flooding, because I put too much polish on the sponge. Cleanup was a nightmare, but I think that's kind of to be expected. I wound up just picking off the excess polish in the shower.
Despite the difficulties, I can see why gradients are so popular right now! All the flaws you can see in the macro shots aren't visible from a normal distance, so it looks really cool in person. Kinda reminds me of some sort of fruity summery drink.
I've already shown you Ole Caliente, but here's a photo of Sun Kissed that I took a while ago, under artificial light. It's actually a lot more yellow-toned than you'd think based on my photo of the gradient.
The formula is...not good. It's really thin and watery, and needs 4 coats for opacity. It is very bright and fun though, and the drying time wasn't as bad as I was expecting.
Thanks for looking and commenting, and enjoy your weekend!
