During the game, the home team usually wears their own home jerseys, and the away team wears away jerseys. In a game like the World Cup, regardless of the host and guest, both sides will draw lots to decide whether to wear their jerseys at home or away. If the colors of the jerseys of both sides of the lottery conflict, they can be coordinated. In short, we should strictly distinguish the colors of the jerseys of both sides during the game.
