My mean chameleons have never become super docile, but they did noticibly relax around me, they don't run for the hills when they see me now. I still can't hold them with my bare hands but they let me get within inches of them without fuss. So I also hold to the opinion that they might have less stress gneerally if they don't think that they're caged in.
Good luck with your guy! The free range looks good!
I dont think you can "tame" all of them like you have mentioned. I think all of the "free ranging will make your chameleons love you" threads and posts have givin false hopes. If the animal doesnt like you its not going to like you. Does a free range make for a happier cham? I am sure it does especially the larger species confined to the suggested cage sizes for them.
Although, kinda funny and scary at the same time which also means they can be just as happy in a good cage. It was warm yesterday and today so I put a few lizards outside yesterday morning. Well, sometimes I only latch one of the cage latches when inside (laziness maybe). I took the animals outside, watered them and left for work. It was windy and somehow I must have unlatched one of the latches bringing the cage outside. The wind blew the door open. When I got of work hours later the one cage door was wide open!!! Im like, OH NO

I look in there and the animal was still in there. Very Lucky!!!
Morals of the story. Double check everything when animals are outside. Also, providing the right sized cage and right micro environment will make for just as happy as a cham as a free range. It was proven in this instance where the animal had full roam of my yard, city, state, country, continent and world but he chose to stay in his cage regardless.
The free range looks good but dont expect it to make your cham want to be held. Bright colors do not mean relaxed either and can also mean stress just as dark colors can. Also, its AMBILOBE not amibole
