If you haven't studied the ol' color wheel in a while, here's a refresher, courtesy of manicurist Wanda Ruiz. To create these mustard-colored manicures for Karen Walker, she custom-blended two polishes together. Seven drops of CND nail color in Blackjack were added to CND's Bicycle Yellow shade, then mixed well. The resulting hue, a slightly murky yet simultaneously bright shade, was an out-of-the-ordinary complement to Walker's collection.
