"four-color deck"的定义和意义

What is a "four-color deck"?

A four-color deck is a variation of a standard deck of playing cards where each of the four suits is represented by a different color. Typically, in a standard deck, the suits of hearts and diamonds are red, while the suits of clubs and spades are black. In a four-color deck, the suit of hearts is red, diamonds are blue, clubs are green, and spades are black. This variation makes it easier to distinguish between suits, especially in games where multiple suits need to be played or tracked quickly. The cards still follow the same basic structure as a standard deck, with 13 cards in each suit, but the different colors help players identify suits more easily.
