Gundam Card Game colors: what blue, green, red, purple and white do

The five colors

The official Comprehensive Rules say there are five card colors: blue, green, red, white and purple. All cards have a color except Resource cards and tokens, which have none. The card list on the official site has a color filter.

A color is a property of the card. It can be referred to in card text, and the rules add that the color of a Unit in the battle area is not affected by the color of a card paired with it. For how Pilots pair with Units, see our guide to the card types.

One or two colors per deck

The rules for building a deck are strict and short. A deck is exactly 50 cards built from Unit, Pilot, Command and Base cards, with up to four copies of cards sharing the same card number. It must be built entirely from one or two colors. The rules give two legal examples: a deck of all red cards, and a deck of green and white.

The 10-card resource deck is separate and is built from Resource cards. It has no color, so it does not count toward the limit. So color is a choice about your 50-card deck, and the Resource cards do not change it.

What each color does

The official rules and site do not assign a fixed role to each color. Card effects are written on the cards and change with each new set, so treat any list that says a color always does one thing with caution.

What the site does show is how its own decks use colors. The next section lists those descriptions as the site words them. They are short deck summaries, not rules.

How the official decks use pairs

The official deck page lists example decks by color pair. Its short descriptions are a good map of the game's styles.

• Blue and white: a midrange deck that starts strong with low-cost Units and enhances attacks mid-game by linking with Pilots.
• Green and white: a ramp deck that builds up resources to deploy powerful Units, and a well-rounded Exia deck that puts a stop to the enemy.
• Blue and green: a deck that chips away at shields with low-cost Units, then breaks through with Link Units and Breach effects, and a Cyclops deck that overruns the enemy with Unit tokens.
• Red and purple: a Minerva Squad deck described as wanting to attack, attack, attack.
• Purple and white: a Minerva Squad deck described as doing both attack and defense, and a Vulture deck that goes on a rampage fueled by the trash.
• Red and white: a G Gundam deck built around Special Moves.
• Red and green: a CB deck that combines deep consideration with reflexes.

How to choose your first pair

Start from the play style, not from a color. Read two or three of the deck descriptions above, pick the one that sounds like how you want to play, and build around its colors. If you are new, the official starter decks are a safe start and the game's own play guide explains the rest.

Keep in mind that the color of a Unit is not changed by the card paired with it, so your pair of colors decides which cards you can put in the deck, nothing more.

When you want a second color, look at the cards you already own. A collection that is heavy in two colors makes the choice easy, and the card list filter shows what exists.

Mistakes to avoid

Do not put a third color in the deck. The rules count that as an illegal deck. Resource cards and tokens have no color, so they do not count toward the limit. Do not copy a color pair from a deck list without reading what the cards do, because the sets change and the list may use cards you do not have.

If you are unsure about a ruling, the Comprehensive Rules are public and updated. The rules cited here are version 1.9.0, updated September 11, 2026.
