Pascal's resting color is this lovely green, not too bright but plenty peppy. I haven't seen any other chameleons, but I'm guessing they're the same.

[What is this cynic you speak of?]

They don't, especially not humans here on Cybertron. Adapting isn't always easy, but sometimes you can't fight fate, you know? Don't get me wrong; I do miss Mother dearly and I'd love to see her again. But I really don't think she'd do so well here. It's... better -much better- for her to be back home.

[Granted, only if time isn't passing there. If it is, Gothel has probably been dead for quite some time.]
