Best way to breed a Triple Rainbow Dragon?

[Starwulf99]

I have a minor obsession with the Rainbow dragons and after I get this damnable Gold Dragon(diamond+air) to breed(5 days and no Gold yet ><) I plan on attempting to breed the Triple Rainbow. Unfortunately it looks like the best combo still has a ton of possibilities, 78 to be exact(The combo being Charisma + Rainbow). Is there another combo that can result in Triple Rainbow with less combos, or am I just pretty much looking at 2 or 3 months of breeding to get this sucker?

Not really. Rainbow and Pink will both split. Took me forever. Got it with Rainbow + Pixie
