Is this their gravid colors? She was breed 4 weeks ago Saturday. She is showing any signs of wanting to lay. I have read 3 - 5 weeks is how long they are gravid true or not? I know each chameleon is different. She is a very dark green.
She looks dark and if she's started to display this colors since she was bred it's quite possible. Normally though from my experience my gravid females have colors similar to the picture linked.
