In my experience, this is not true... sorry.
My red-eye is always darker at night, when the lights are out. Even with high humidity and perfect temps. When lights come on first thing in the AM, my red-eye appears darker, like Lynn's Ruby.
Lynn is a very experienced frog owner, I would only be so lucky to come back as one of her frogs!
