Four-Color Deck

A four-color deck is similar to a standard deck although instead of having just two colors — black for clubs and spades; red for hearts and diamonds — each of the four suits has a different color. Typically in a four-color deck hearts remain red and spades remain black, while clubs are made green and diamonds blue.

Most online poker sites have an option available for players to use four-color "decks," which many players agree makes it easier to distinguish suits at a glance when viewing on a computer monitor.
