I haven't taken many shots since the initial setup. Here's tonight:
I covered the back of the tank with frosted window privacy film and rigged a Phillips Hue programmable LED behind it. This is the evening mode; sort of golden. It is pink in the morning, around 5000k white during the day, gold in the evening, and red at dusk. It stays a muted faint blue at night. I had to cut foam board to create a "box" behind the tank to keep the light from leaking out into the room.
