to get back to the from you want you will need a platinum female then breed out the colors this is a long process to get what you want you just have to keep breeding and selectively choose the best specimen and breed from that otherwise it wont revert back to the original genetics.it took me around 2 years to get a full black tuxedo moscow blue completely black/blue but it can be done in a shorter time span if u have multiple specimens.u can use plain females but its very difficult because they would have had to come from some genetic pool and will be near impossble to tell which color variant it is
