Oversize cards are also produced. These can assist with ease of handling and to allow for larger text. Some decks usefour colors for the suits in order to make it easier to tell them apart: The most common set of four colors for poker is black spades, red hearts, blue diamonds and green clubs (♠ ♥ ♦ ♣). Another common color set is borrowed from the German suits and uses green spades (leaves), red hearts, yellow diamonds (bells) and black clubs (♠ ♥ ♦ ♣).
