To do these, I painted a base of Models Own Snow White to make the neons pop. I then used the make up sponge method (there's a tutorial here I did) to apply the neons - I wanted a rainbow effect but the green/purple nail didn't really work! What I'm looking for is a proper neon blue polish, but I haven't found one yet. In hindsight these probably would have looked good with some sort of black nail art over the top. Ah, there's always a next time, right?
In direct light
Have you tried the Ice Neons yet? Which one is your favourite?
