I see your cham is located in the livingroom. Sometimes chameleons get stressed about the flickering lights from a TV. Could be something as easy as that if he has a TV visible for him but the experts might be here soon and give you some better idéa from what you wrote

Good luck!

My cham sometimes gets darker when she's upset or angry, i have her outdoor and when i get her out of the cage and put her in other trees she turns soft green and sometimes show some yellow, black, blue, orange spots all over her body, and then she start lookin for some other insects and ground bugs arround the garden and eat them. I think is because shes bored i don't see nothing else when that happend all i do is take her out and she's good. Try to give him a diffrent place to hangout sometimes so he don't get bored.

Hopefuly to help u with this info!!
