What defines the domain of a card?

According to Rule 134, a card's domain is defined by one or more symbols located in the lower-right corner of the card. Each domain has an associated color, a unique symbol, and a shorthand notation used in text:

• Fury: Associated with the color red and represented by a circular symbol with three projecting points. Shorthand: [R].
• Calm: Associated with the color green and represented by a leaf-like symbol. Shorthand: [G].
• Mind: Associated with the color blue and represented by a sun and moon symbol. Shorthand: [B].
• Body: Associated with the color orange and represented by a blocky diamond-shaped symbol. Shorthand: [O].
• Chaos: Associated with the color purple and represented by a hexagonal symbol with swirls. Shorthand: [P].
• Order: Associated with the color yellow and represented by an angular winged symbol. Shorthand: [Y].

For colorblind accessibility, you can also identify a card's domain by the symbol itself at the bottom right of the card, or by the color of the bar behind the card's name (as noted in RiftJudge FAQ 6342).
