Chromatophores are the cells in a chams skin which cause it to change color. I am a sophomore in college and gave a presentation to a cellular biology class on this topic. I used my male veiled as an example and got raves. You'd be surprised how many ppl have never even seen a cham in real life. Everyone was very interested, including a man with his doctorate in cellular biology. Pretty impressive for a lizard thats only a juvie!! LOL. Keep educating and good luck keeping your chams.
