First, the white fondant needs to be colored gold, too. To achieve this use yellow, a tiny bit of red and a tiny bit of black. Then, after you have made the hearts use gold luster dust and either lemon extract, vodka, or Everclear to create a paint-like consistency and paint the hearts gold. It might take a couple of coats but will be very shiny and gold when you are done. If you use the luster dust directly on white fondant you will not get the same depth of gold plus any tiny spot you might miss with the luster dust will not show as much on the finished cake. HTH
