veiled coloration

[kidchameleon]

my veiled is 4 months old now, and her colors look like they have darkened. when i first got her, she appeared to be a light green, with some orange. now she looks like a greyish-green.. its not stress, because when she gets stressed you can see the dark bars and spots. i know chameleons dont really start showing too great of colors until around 5-6 months of of age, but i am curious on how she was more colorful in the beginning then now. thanks
