FR, did they post more pictures of the darkening colors of those particular savannahs over the years, or are you basing that off of conversation you had with them? I've just never seen anything like it, I remember coming across a few reports with questionable validity, but never heard anything about the colors going away. To an extent, that would be similar to what happens with varanus dumerili right? - with the severe difference in colors and patterns as they age
