Like its parent game Magic: the Gathering, Color in Magic: the Gathering Puzzle Quest is a core mechanic whose thematic flavor influences all aspects of the game.
Each of the five colors — White (), Blue (), Black (), Red (), and Green () — is associated with distinct principles, and different mechanics and abilities.
|White||Peace, law, structure||Plains|
|Blue||Knowledge, intellect, deceit||Island|
|Black||Power, selfishness, death||Swamp|
|Red||Impulsiveness, freedom, destruction||Mountain|
|Green||Nature, growth, interdependence||Forest|
Most Planeswalkers have an affinity to one, two, or even three colors. A Planeswalker's deck may only include cards which have a color matching an affinity of the Planeswalker, as well as colorless cards.
Planeswalkers also have a mana bonus for each color. The bonus is typically larger for colors the Planeswalker has an affinity to.
In Events, some nodes have color restrictions. Such nodes may only be played by a Planeswalker sharing a color with the node, or a colorless Planeswalker.
Each card is either colorless, or has one, two, or occasionally more colors.
Card abilities tend to be thematically linked to certain colors.
Ability separation by color is weaker in Magic: the Gathering Puzzle Quest than Magic: the Gathering for two reasons:
- Card design follows color principles less strictly
- Dual color cards can be used by any Planeswalker sharing any one of those colors, so any color-specific mechanics on such cards are more easily accessed.
