Certainly, no! You can't change the back color of check-box, but you can
use a trick. Set style for check-box to 1-Graphical, remove Caption
and set Back Color to required. Resize them to approrpiate size.
Макe a small picture with desired size and color and point to it the check-box property DownPicture. Then add near the check box label with desired caption. That's all.
