Not an expert on anything, BUT - since darker colors absorb heat & light colors reflect it, it's probably a heat-absorbing reaction. Just read that gray tree frog does a similar thing:
"Gray Treefrogs are medium-sized frogs, usually with a light greenish to brown gray color. When placed in low temperatures, their skin will become a charcoal-gray color, but when placed in a warm or sunny area, they will turn a silver-gray color with green highlights." - http://library.thinkquest.org/11034/gtreefr.htm
I've read that ball pythons darken in cool temps also. ~~~Interesting & not really related - you know the kind of cats & rabbits that have dark-colored noses/tails/paws/ears - like siamese? I read that the fur color is related to body temp, hence the extremities being darker color than the body. Some scientist kept a cold-pack strapped to the back or side of a color-pointed cat or rabbit, & the new fur grew in the dark color.
Animals are weird :-)
:I notice that when my tank temp goes down, my FBT seem to go darker...real dark. I know that darken when shedding skin but I noticed that this happens when it cools of in there as well. As soon as it heats up again, they turn lime green again. With in a few minutes. Is this merely coincidence? Or could it be that temp effects there color too? (FYI, please don�t read to much into this...I am not 'freezing' my FBT. I�m talkin� going from 78 to 73 degrees to 79 again more or less a bit. I'm in Denver so it gets cold at night no matter what I do. I just don�t want you to think it going from 85 to 60 degrees or anything...;-)
