Love or Lose: One Nail Different. I read in Cosmopolitan that celebrities are doing one nail an eye catching metallic while leaving the other nine a muted color. At first I thought it was an April Foolâs Joke, seriously, who would paint one nail a different color? But after I gave it a try for a night out, I have to admit that the creative manicure set off my cocktail ring beautifully and made it look as though Iâd spent ages planning it all (really it was a happy accident).
