Started with a base of Silver - Sinful Colors Out of this World
Used a dotting tool for the dots.
Black - Sinful Colors Black on Black
Teal - Sinful Colors Rise and Shine
Robin's egg blue - Wet n Wild MegaLast Salon Nail Color I Need a Refresh-Mint 218A
Only tricky thing about this is trying to make the dots look random. Making the dots themselves are super easy.
