This little chameleon did a fabulous job turning bright turquoise blue! His throat and entire underbelly were the bright color, but I only caught the top of him on camera --
-- before he went back to his regular color. He did, however, continue to pose for quite a while, and I got several good shots of him in camouflage mode. He stuck around so long I was able to do a lot of experimentation with the manual settings on my camera, too.
I'll be watching to see him again, hoping to catch him BLUE!
