Hi...I've never kept an iguana, but when I belonged to a large herp society, some of the members brought a large male (rescued) iguana on a leash to help educate
others about the pitfalls of keeping them. (one that one had worn out his welcome by attacking the woman of the household & not allowing her to go upstairs...really!)
Anyway, that iguana was actually orange in color when he was at the show, & was known to be quite healthy, so I'm guessing that the color change you're seeing may
be the very same thing? I don't know how many iguana keepers are around on this forum, & it's been a little quiet lately anyway, so that's why I'm taking a crack at
your question. I do not know if only one gender changes colors that way, or if they both do. If your iguana is eating like normal & acting healthy, she's probably fine.
But if you need to find a vet, or just want to have "her" (?) checked up, this site may help you find a qualified vet nearest you:

BTW, IF your iguana happens to have been mis-sexed & is actually a male, and IF you are a female of reproductive age, you need to be aware that more than one owner
has had issues of aggression from adult male iguanas towards adult females in the household at "that time of the month". Something (scent-wise) apparently just sets
them off, so please be forewarned, as large iguanas can truly hurt you to the point of needing hospital care. A whack from their tail has been known to cut a man's arm
to the bone, plus they can bite & have claws. Please do be careful no matter how docile "she" seems to be at this stage. Wild animals sometimes grow up with unpredictable instincts that influence their behavior.
And please do update us with whatever you find out, OK?
