In casino gambling, particularly in card games like blackjack and poker, the term "paint" refers to face cards, which are the King, Queen, and Jack. These cards are often associated with higher values in the context of the game, with Kings and Queens typically valued at 10 points each in blackjack, while in poker, they can be part of high-ranking hands. The term "paint" is derived from the illustrations or "painted" images on these cards.
