Personally I'd use the original parents. I'm really not entirely sure what you are going to get spawn wise. I think the black and green will get you irids-turq, steel blue, copper, blue maybe green-nothing black. Possibly black heads because he is black and she her color doesn't cover her head. Red could pop up because I don't know what is under Supermans black layer.
The other pair will also probably give you irids. He looks like a pastel steel blue(platinum over steel blue). She's light bodied. Since you are breeding to irids in both cases you will likely get irids because irid is the top layer and it covers up the other layers. I think you may get pastel blue, steel blue, turq. and some degree of marble. That's only my guess though. That's why I suggested switching them for the next round of spawns because you'd be breeding within the same color layers. Cambodian and blonde is in the black layer. Platinum, Steel blue and turq.(green) is in the irid layer. Definitely keep us posted!
