Young adult male. The picture doesn't do him justice. I got this guy a short while ago, initially I though he was a bluish hue, but it's definitely more of a lavender when fired up. Nice yellow too.
Picture taken with a Sony Cyber-Shot DSC-F505V. No flash, just a 15 watt Philips fluorescent strip light overhead. He probably would look better under a full spectrum reptile fluorescent, as they give of a blue hue compared to the normal store bought fluorescents.
