Colorless mana is a type of resource used in the game Magic: The Gathering. Unlike colored mana, which comes in five distinct colors (white, blue, black, red, and green), colorless mana is represented by a different symbol and is often associated with artifacts and certain lands. It is used to cast spells and activate abilities that do not require any specific color. In the game, colorless mana can be generated by specific lands, such as Wastes, or by certain cards that produce it. This type of mana allows players to access a broader range of strategies, particularly those focused on artifacts or colorless creatures.
