Color Energy

Color Energy is what allows the power of color to be utilised. Almost everyone has a slight amount of Color Energy. It is an incredible rarity to have an excess of this energy, but there are few who do; Inani Watsuki is one of those few. As well as humans, Color Energy can be found in animals and plants, however, demons and tortured souls possess no such energy.

Traits
Higher levels of Color Energy make the subject stronger and more energetic. Color Energy also allows the power of darkness to be countered. With high levels of Color Energy, it is possible to restore energy to things and people. Color Energy also provides life and without it, plants and animals alike would die over time.

Darkness and The Black Katanas
The power of darkness is only utilised by the Black Katanas. It has the opposite effect as Color Energy; it drains energy from things and people. Masayoshi Watsuki used this ability on Inani to rid her of her Color Energy. Darkness often doesn't have an immediate effect. When darkness is inflicted upon someone, the darkness leaches upon their Color Energy and slowly depletes it. Once someone has all of their Color Energy depleted, they become Faded. Faded people become sick and weak.
