Does fish color fade at night?

In the morning when I turn on my lights, I notice that my 3 stripe damsel is faded. Within about 30 seconds or so with the lights on he is back to his normal bright black and white. Is this a sign of stress or is this something that is normal? During the day, there is no fading. I only notice it in the mornings when the lights are first turned on and his color comes back fast.
