Copy effects, such as Spitting Image and Clone, copy a permanent's mana cost (and all the mana symbols therein).Similarly, Primalcrux (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. For example, Heartlash Cinder's chroma ability includes itself, so it'll get at least +1/+0. Many chroma abilities check a set of permanents that includes the one with the chroma ability.For example, a card with mana cost has two red mana symbols in its mana cost. Chroma abilities count hybrid mana symbols of the appropriate color.They don't count mana symbols that appear in a card's text box.

Chroma abilities check only mana costs, which are found in a card's upper right corner.Different chroma abilities have different effects and check different sets of cards or permanents.
