I used a white Sally Hansen varnish as the base and then another Sally Hansen varnish in 'Kook-A-Mango' (No 560) for the orange tips. I also used a glitter topcoat from Revlon in 'Belle' (mainly to disguise the slightly dodgy colour change). Ideally I would have used something like a foundation sponge to apply the orange, however, I didn't have any so used a cotton pad, which I surprisingly found left little fibres all over my nails! Never mind. A quick coat of the topcoat and it's barely visible!
