Re: SMART board colour issue
Make sure the VGA cable is plugged in all the way on both ends.. If a pin isn't making contact it can make a single color be the dominant color shade. If both ends are secure, try a different cable. If it still does it, try it on a different SMART board. If it doesn't do it on the other one, then probably a bulb issue. If it does do it on another board, then it's an issue with the computer.
