I knew the colors varied, but wasn't expecting that much. When I bought my second frog, I commented on how dark he was and the guy at the store said he'd lighten and that he was probably just cold. They keep them with the anoles, so I kinda doubted that. He lightens up at times, but is still a dark frog, I like it.

Sorry, crappy cell phone cam.

They finally got names, brown one is Yoga Zen Frog, green one is Sushi.
