What is the difference between Yellow Cards and Red Cards in Football?

When you are watching football, you may notice that there are different cards that are raised depending on what the player has done. When the yellow card is raised, this is meant to show a warning to the players. This can be considered as a cautionary card.

When the red card is already raised, this means that the player is being released from playing. The player will not be allowed to return and to play for the rest of the game. Yellow cards are known to provide milder punishments but players would need to take more care into doing the things that they do if they would like to keep on playing.
