At each end of a major cricket ground is a 'sight screen', which is of a contrasting colour to the ball; white screen for a red 'day' ball; black screen for a white 'night' ball. The screen is moved so as to be behind the bowler from the perspective of the batsman. The ball thus stands out from the background and assists the batsman in making decisions about his shot. | At each end of a major cricket ground is a 'sight screen', which is of a contrasting colour to the ball; white screen for a red 'day' ball; black screen for a white 'night' ball.
