Color (色 iro) is a fundamental card quality.
Five colors exist in the WIXOSS TCG:
Some cards have no color. These cards are considered to be colorless.
A deck's predominant color is typically determined by the color of its LRIG (or more specifically, that LRIG's grow costs and the color of the cards that specify that LRIG for its limiting condition). Players may use cards of any color in their deck regardless of the color of their LRIG, except in the Diva Selection format, where players may only use cards of the colors of their three center or assist LRIGs.
