A player’s palette is the group of cards which that player has played throughout the game, those cards are used to judge who is winning the current rule. On their turn, a player can play one card to their palette and/or play a card to the canvas. The starting rule is simply that the highest card wins, with ties being broken by a color power ranking chart, which is constantly available on the side of the screen. Cards are numbered one through seven and are, you guessed it, one of seven different colors.
In Red 7 each player is dealt a hand of seven cards along with one starting card, played to their palette, to being a game.
