Depending on what you style is and why your painting your nails. If your going to a wedding, it's best to do white with whatever the wedding colors are. Don't be afraid to experiment!(: If your bored, find some colors that look good together like silver crackle with neon purple. It's your style, nobody else's. So why should you care what people think? P.s. it also depends on your outfit!!!
Neon colors using gel nail polish or regular nail polish. Oh,and you can also try putting black as a base coat and putting 4 different rows of different neon color dots.Ex...One row Mint Green of 4... The other row Orange of 4...etc.
