: What you suggest is not a genetic thing but just forced modifications. Anyhow, I doubt that that may work with Iguanas, since the eggs of green igs are extremely sensitive against temp variations. So if you change temps after the first half of the incubation, Iggie eggs will die.
To produce colour variants you have to weait for mutations and than do carefu� selection. Excessive inbreeding may bring out color morphs earlier (a similar thing are those feral Igs...ever heard about gene drift?)but harbours high risdk of bringing out negative health and viability threatening traits. So be patient: The more Igs will be captive bred, the more mutations will show up and within a few decades you may find at least white, yellow, black and blue Igs which all can stem from single point mutations. So its very likely that these phases will come up.
Whether it makles any sense to breed such animals is anothe rpoint....
