I'd like to see a perfect red. Of how about a true green? You stated black and it is THE most difficult color for an experienced breeder to work because females, the dark ones, produce infertile eggs. So often spawn after spawn fails. And you have the irid issue. THAT is why you are being told to research because most of us that HAVE been around and bred these fish know these difficulties and your question tells us you do not have a clue about what you are trying to get into. We also know telling you we want a tri band red, white and blue fish is stupid because you are not going to even know where to START breeding for this. I've been breeding for years and have been successful at it and only recently do I feel prepared and qualified to work the color black. It is not a color for a beginner to start with.. but after 2 weeks of research [not experience] I'm sure you are going to tell me otherwise.
And what is your end goal? To show? Then best breed to the standard and try perfecting a solid, other than black. Even the patterned fish are difficult to achieve the standard. And they have to have good form on top of it all.
If you just want to breed some genetic mutts with all kinds of crazy colors do what ever will hold your interest. Your fish will end up [hopefully] in a local fish shop as a serious breeder is not interested in genetic wildcards. And unless you participate in and do well in the shows.. again, the serious breeder will not be interested in your fish. You may be able to sell an interesting one here and there for a few bucks on AB.. but you sure will not even break even in your hobby.
Best advice is breed fish you like.. what we think makes no difference when you spend 4 hours a day doing water changes.. only what you think matters then.
