Here's a dark version of ombre nails. I used Dior 804 Perfecto as my base coat (2 layers) and Essie Going Incognito as the top colour which I dabbed with a sponge. Done that, I decided that it was not enough, so I applied with the same sponge Golden Rose Paris 151 (dark green - not in the picture) just at the tips of my nails. Once it dried, I used Essence Studio Nails Better Than Gel Nails Top Sealer as my top coat.
Hope you like it,
