How do you make a chroma frog in pocket frog for iphone?

Easiest way to get a Chroma frog in Pocket Frogs is to have one sent to you as a gift. I'm all about trading the Chromas. Send me something good (level 12+ or a Chroma) and I'll send you a Chroma (I have two kinds right now and am working on breeding more!). My Plus+ account is Sim2737
