The color indicator ({CI_W}, {CI_U}, {CI_B}, {CI_R}, {CI_G}) is a characteristic of an object. It is printed to the left of the type line directly below the illustration. It consists of a circular symbol filled in with typically one but sometimes more colors. A color indicator is usually found on cards without a mana cost that however have to convey color information.

History[ | ]

The color indicator was introduced with Innistrad to define the colors of the back faces of double-faced cards without resorting to characteristic-defining abilities.[1] With the following Oracle update, some cards (such as Crimson Kobolds and Evermind) received errata, removing a characteristic-defining ability defining the card's color, and receiving a color indicator instead. This produced some functional changes, such as Crimson Kobolds being affected by Muraganda Petroglyphs, and players being unable to splice Evermind onto Arcane spells in order to change the original spell's color.

Multicolored color indicators[ | ]

Multicolored color indicators exist usually when the backside of a DFC is multicolored, which is a narrow intersection of mechanical design. Sets from Innistrad previously held the collective greatest number of these, but March of the Machine's multicolored Battles and Phyrexian transformations put thirty-three in one set, with multiple full complements of color-pairs. Asmoranomardicadaistinaculdacar is unique in that the name length prevents having a conventional mana cost, making it the only single-faced card with an indicator.

Three-color indicators are rarer, as designing enough three-color cards are already difficult: there are three Premier set cards with a tricolored indicator. Incidentally, all are legendary creatures. Outside of that, the Transformers Universes Beyond product has four cards having tricolored indicators that are colored more by character rather than by mechanical purpose.

Five-colored[ | ]

For a while, Transguild Courier featured a five-colored indicator in Gatherer but was never printed with it. When a five-colored indicator was considered for Sphinx of the Guildpact, no version was deemed suitable for printing. This resulted in the use five-colored indicators to be abandoned in favor of characteristic-defining abilities, and a similar oracle update for Transguild Courier.[2][3]
