What are the differances between a red card and a yellow card in team handball?

According to the rules of the International Handball Federation, A yellow card is a warning. You can only get one yellow card per player and 3 yellow cards per team. A red card is for disqualification. If a player receives a red card, they are suspended for the rest of the match. The team will continue in numerical inferiority for 2 minutes.

The International Handball Federation has a helpful guide called "Handball Rules for Beginners." You can also find more information on their website (I wish I could add the link for you ihf.info)
