I too have a problem with the ball color. Being the tallest member of my team I would be the obvious choice for our human player because I can more easily negotiate the height of the wall. However, I'm blue-purple color blind and can not tell the difference between the moon rocks and the empty cells. I have not had a chance to read all of the comments to see if anyone has any ideas but I do hope that FIRST will find a solution to this problem before competion.
