i think anything will be fine except for opaques, washes, blacks (both lace and melano) marbles, etc. the ones that shouldnt be beginners bred. I'd suggest (like Alexa) red, green, blue. the more solid colors. but if your like me and go by statistics of who likes them, then go for it. I'm planning to breed my Black Melanos, Yellows, and Steel Blues. Have fun john breeding, keep us updated too!
