Create a Custom Nail Color
A true nail polish addict is never satisfied with just one shade of red. But you can give one bottle of crimson polish more life by adding another shade underneath. For instance, you can give it a darker feel by adding brown or a brighter vibe with orange. Deborah used a similar technique backstage at Kate Spade New York to produce a rusty brick red. First she laid down one coat of Knock on Wood, then topped it with My Old Flame ($18). The secret: "You have to let the first layer dry. You'll get drag and not the right kind of coverage if you don't really let that first layer dry for two minutes before you put that second polish," Lippmann says.
