Camera Color Recognition Problem?

[AnkurG]

I was just thinking that at the actual regional, the vision tetras will be on a field that is lighted by many floodlights. This lighting would potentially change the color of the green a little so the camera would not see what it was originally calibrated for. Does this mean that we would all have to recalibrate the camera at the competition as well? If so, then how exactly can we recalibrate the camera with the lights at the competition without actually walking up to the side of the field? Sorry if this question has been asked on the forums already.
