The color pie continues to play a huge role in Magic's gameplay and its status in popular culture.

Using multiple colors in the same deck introduces the risk of drawing spells of one color, but only drawing land cards that produce mana of another color. The color pie system was created by Richard Garfield during his original design for Magic: the Gathering as a solution to a critical problem of the budding trading card game genre: how do you stop players from simply putting all of the best cards in their deck? Almost every spell in the game is tied to one of five colors (in their conventional cyclical order: white, blue, black, red, and green) and requires a correspondingly source of mana to cast. What's the color identity of your favourite fictional character? Why are black and red allies, but not black and green? Why is head designer Mark Rosewater wrong about that aspect of blue? Who on earth thought that card was actually a white effect? What color are you?
