Jeff,
Oh, I know it's not proof of anything. This guy could be a loony bird for all I know. I just thought it was interesting, that's all. 
Having said that, it could work for Indigos but not BRB's.
I wouldn't rule that out, pigmentation might work completely
different in Indigos.
After all the reading I've done and information (from people such as yourself) that I've tried to process, I actually don't believe that rainbow boas have as much erythrin as one would think (or as I originally thought.) My speculative opinion is
that if it's even possible to isolate the right carotenoid for
Rainbow Boas (there are hundreds of them!), I would expect it
would only enhance the color of the dorsal patterns and crescents.
But you made my day regarding the carrot diet. I hope it
works!! If not, at least your rats might be a nice shade
of orange. 
Thanks,
Ed
>>Ed,
>>....That one poster over on the Indigo forum seems way too sure what in reality is just an opinion. When I used Nekton Rep Color I did not set up a control group and there was no way that I could have reasonably measured results. My unscientific impression was that the Nekton Rep Color made no difference. The babies I am producing today are noticeably more colorful but this is likely the result of selective breeding. However,.......after reading some of the links you posted over the last few months about color synthesis in animals I have recently been feeding carrots to my rats along with their Mazuri 5M30 Rodent Chow and occasional table scraps.
