Mustard gas is really nothing more then green yellow bicolor. The very best ones ..that haven't been seen is a while.. were green/yellow/green butterfly. If I was oging to try to start a "MG" line I would pick up a black/yellow and cross it to a green iridescent female. From there I woud plan on working 5 or 6 generations to even begin to see results. After all that work I would cross in to my royals, but it would never produce more than a fish or two that "might" look purple in the right light. IHMO A much better way to produce purple would be to cross metallics into a iridescent line and start selecting for a "purplish" color in each generation. The "purple" you see on aquabid are from metallic lines. Since I've never seen one in person I can't say if they are really the color they look on Aquabid, but I have my doubts.
Are far as getting Blacks from a multicolor cross.. you are working a very LONG road. You will start to get some Blacks in a few generations, but they will be so covered with other colors they will look like crap. It will take some very careful selections of generations to really start to get "good" blacks. Also if your muliticolors carry melano then ALL the black females will be infertile. I'm finding the Double Blacks are starting to produce some nice colored blacks with very little iridescent problems.
