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).
Make sure the temperature of the chocolate rises to between 104 F. and 113 F. when melting. Do not heat above 115 F. (milk and white chocolate) and 120 F. for dark chocolate, otherwise it will burn. Chocolate, especially milk chocolate, is very sensitive to heat and will scorch or seize easily.
