Hi...
There may be a color balance issue causing the problem. Do you have your colour profile settings correct and your monitor drivers correctly installed?
Really the easiest solution will be to use Photoshop to remove the background of your character image and save it in a format liken PNG which will keep the transparent background. Then setup the complete character in CrazyTalk (not just the head part). Finally just add the background you want in CrazyTalk which will eliminate any color differences.
