Try using the milk chocolate melts with some black coloring for the black and some white chocolate melts with the yellow and black colorings for the gold (reminder: use the black VERY sparingly).
All chocolate is made of the same 3 main ingredients....cocoa butter, cocoa solids and sugar. The ratios in which these 3 ingredients and other flavorings, such as vanilla, are mixed is what makes the different types of chocolate. Dark chocolate has more cocoa solids than anything else...giving it it's richer flavor.
