Yes, I've heard the temperature/humidity theory as well, but the way my frog reacts is an indicator that it's related to his mood as well. I've also heard that the more green things you put in your viv, the more green your frog will be. All three of these theories seem like they're supported by strong evidence, so I don't know which one to believe. XD

That would be neat because they don't have really distinct facial expressions, so if they change color based on their mood it'd be easier to fit their needs.
