I have kicked around this idea a couple times over the past couple years but couldnt raise interest enough (data) to make it worthwhile. I would ask how many N.American milksnake breeders would use a standardized color template to quantify color differences. I suggest a yearly color test to each milk and records kept-- primarily incubation temps and parental colors. As far as I know there hasnt been anything like this attempted and data accumulation would likely take years to quantify...but most NA milk breeders would directly benefit from results.It would also make good photographs redundant.I would say at least 10-20 breeders would be necessary to bother to coordinate this.Either post a follow-up or email me with your input.Thanks,Jeff
