The color indicator 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 one or more colors. A color indicator is usually found on nonland cards without a mana cost.
History[edit | edit source]
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.  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.
