A yellow card is a warning, two yellows make a red, a player is sent off when shown a red card. They can also get a straight red for a serious offence.
Depending on the level of the foul or bad behavior (taking someone out by purposely harming them), a player may receive a yellow or a red card. The red card is more serious.
