Chroma

Chroma is an ability word first introduced in Eventide. 
==Description==
Cards with chroma require a count of the number of specific colored mana symbols on cards. This mechanic was first seen on <c>Phosphorescent Feast</c> in Future Sight, but first named in Eventide which also saw a reprint of that card.
Chroma was tweaked and reintroduced in the Theros block as devotion, where it limits the counting to permanents. A version of Chroma without the ability word that references the stack appeared on . 
==Rulings==
*Different chroma abilities have different effects and check different sets of cards or permanents. Read each card carefully.
*Chroma abilities check only mana costs, which are found in a card's upper right corner. They don't count mana symbols that appear in a card's text box.
*Chroma abilities count hybrid mana symbols of the appropriate color. For example, a card with mana cost has two red mana symbols in its mana cost.
*Many chroma abilities check a set of permanents that includes the one with the chroma ability. For example, <c>Heartlash Cinder</c>'s chroma ability includes itself, so it'll get at least +1/+0. Similarly, <c>Primalcrux</c> (a creature with power and toughness each equal to the number of green mana symbols in the mana costs of permanents you control) will be at least 6/6 while it's in play.
*Copy effects, such as <c>Spitting Image</c> and <c>Clone</c>, copy a permanent's mana cost (and all the mana symbols therein). A token that's a copy of a permanent will copy that permanent's mana cost, if that permanent has one, and will be counted for chroma abilities.
==Examples==
==Trivia==
* Chroma was featured as rules card 3 of 8 in the Eventide set.
