The race is on to find the next hot nail color, and the stakes have never been higher. According to the Wall Street Journal, sales of OPI's "Lincoln Park After Dark" polish - the shiny black color - quadrupled last year. The company blames it on Chanel's Black Satin Nail Polish, worn by Lindsay Lohan and remixed by us back in January. Now OPI is pushing "flame," a lacquer the color of a daiquiri, but it seems less likely to make waves than the white and silver polishes seen on the runways this winter. We also like a retro return to Hard Candy's sky blue color. What do you think will be next?
