Color Rank

In the Elemental Council Headquarters, missions are given to the Elementals based on their Color Rank. Elementals can achieve a Ranking by means of the ERT.

Colors
The Color is the name of the Rank. Colors can be divided into two categories: General and Fighting. The General Color is based on the colors of the rainbow, while the Fighting Color is based on precious stones. The Fighting Color is generally regarded as the lesser important color, because not all Elementals have a power that is applicable in a battle.

General
General Rank measures many aspects of the Elemental, and not just battle strength. Traits such as leadership, intelligence, attitude, adaptability, and clever use of abilities are all taken into account.

White - Lacking the qualities of an Elemental. Poor use of ability and no accounts of outstanding leadership or intelligence.

Purple - Novice qualities of an Elemental. Basic use of ability, but no accounts of outstanding leadership or intelligence.

Blue - Novice qualities of an Elemental. Basic use of ability with some accounts of leadership, attitude, and intelligence.

Green - Notable qualities of an Elemental. Above average use of abilities with accounts of leadership, attitude, and intelligence.

Yellow - Above average qualities of an Elemental. Creative use of abilities with strong examples of leadership, attitude, and intelligence.

Orange - Outstanding qualities of an Elemental. Creative use of abilities with admirable leadership qualities, attitude, and intelligence.

Red - Superior qualities of an Elemental. Ingenious and creative use of abilities with superb leadership qualities, attitude, and intelligence.

Fighting
Fighting Rank measures the pure battle strength of an elemental. This ranking was created separately because not all Elementals have a power that is useful for fighting. This way, you could still rank highly without being a decent fighter. The Fighting Color is the second color of a rank, and is only taken into account for missions that require battle strength.

Copper - No battle strength

Citrine - Little battle strength

Amber - Average battle strength

Emerald - Above average battle strength

Sapphire - Admirable battle strength

Amethyst - Superior battle strength

Diamond - Elite battle strength

Trivia

 * The Fighting Color goes forward through the visible spectrum (with copper being a substitute for a red gem) while the General Color goes backwards through the visible spectrum of colors.
 * The highest rank an Elemental can achieve is a Red Diamond. This corresponds to the rarest color of what some consider to be the most precious gem.
