Molly was like that for a long time. She has always been a nervous little thing and showed dark colours most of the time unless she was asleep or feeding. She has settled down the last few months and shows her colouration during the day too now.
The male has always been a show off from day one though and spends 90% of his time coloured up. The only time he dulls is when he is outside.
Weird actually, I have been told by so many people that keeping beardies outside makes their colours better, certainly not the case for my beardies, they are coloured up when inside and they dull right down outside! Guess it's warmer in their enclosure than outside most of the time.
Don't care how dodgy your camera is, pics would be awesome!
