In 1819, J.Y. Humphreys created the "Seminole Wars Deck" which had four colored suits of blue spades, green clubs, red hearts and yellow diamonds. In 1876, for the American Centennial, Victor Mauger issued a deck that contained black spades, red hearts, yellow diamonds and blue clubs.
Four-color decks made for bridge or whist, are often called no-revoke decks because they are perceived to reduce the risk of a player accidentally revoking (illegally playing a card of a suit other than that led.) Many dozens of card manufacturers have developed four colored suit cards for bridge during the 1900s and continue into this century. S.R. Huntley created many Bridge decks, which included his stylized four color pips of black spades, red hearts, orange diamonds and blue clubs. Some of his decks included "forcing" instructions printed on each card for play. In 1947, a deck of playing cards of bridge size, from Forcolor Inc., introduced a deck with black spades, red hearts, green clovers (three-leaved, not the french club shape,) and orange diamonds. In 1948, the Avoid Playing Card Company, introduced a deck of the same name with black spades, red hearts, orange diamonds and purple clubs.
A four-color deck for poker was developed and publicised by Mike Caro. It was introduced at his World Poker Finals at Foxwoods Resort Casino in 1992. His original design was not a success as the colors were a surprise to players. ("Mike Caro's Four Color Deck" by Diane McHaffie, Poker Player February, 2006 issue.) However, four-color decks have become a somewhat popular option in Internet poker software interfaces since often each player may use their preferred design of playing cards without affecting others' experience, and since visibility is not as good on a small screen as in face-to-face play. Having each suit represented by a different color can allow players to more easily recognize a flush. The U. S. Playing Cards Company made a poker sized deck called MULTICOLORS. Hard to find except through online sources. Mike Caro's deck and the MULTICOLORS both use the black spade pips, red heart pips , green clubs, and blue diamond pips.
In the German game of skat the official tournament standard is to use a four-color deck known as a turnierbild deck. In these decks, spades are green and diamonds are yellow, the hearts and clubs being respectively red and black as normal. This is intended as a compromise for players who prefer German suits over French; the green Spades translate to Leaves and the yellow Diamonds to Bells in the German suits.
