Four (4) Color Deck of Cards
Has anyone ever heard of a deck of cards that consist of four different colors! It took me by surprise too! I just heard about it recently on a wikipedia article about them. It appears that they were introduced in the World Poker Finales in 1992. It is used in the German game called Skat too.
The color they use for each suit is Spades are black,Clubs are green, Hearts are red, and Diamond are blue.
I think this is a very interesting idea and I am going to try and pick up a deck of these cards.
