Four Color Deck
A four-color deck is similar to the standard two-color card deck. The only noticeable difference is that instead of having just red and black colors, each suit has its own color.
Four-color decks aren’t as common in live poker rooms, but many online poker sites allow you to set this option when playing.
For example, the most common representation of a four-color deck is black, red, green, and blue. In this color distribution, spades remain black and hearts red, while the diamonds are blue, and the clubs are green.
