Edit: It was brought up in comments whether or not it was possible that the lizard in question could change colors that fast naturally or if it was with the help of CGI. To tell you the truth, I have no idea. All I could really find of substantial relevance was this and this.
This is really cool. Can Chameleons really change to that extreame of colors? Even if they can’t still an awesome video!!
