Psychochromy or Soul Colour(ation) is a way of categorising people based on how their sense of self and system of morality interact with eachother (or don't). It is based on ideas as to the meaning behind the soul types in the video game The Coffin of Andy and Leyley, but regardless of potential accuracy or inaccuracy to said game, it can be an interesting way of looking at yourself, other people, or other characters.
Morality: morality system
Self: sense of self
Note: Morality and Self are to always be capitalised.
Moral. Pure souls have a morality system and a sense of self that are aligned. Refined power.
Extrinsic pure souls are guided primarily by their morality system, altering their sense of self to conform to their Morality.
Intrinsic pure souls are guided primarily by their sense of self, altering their morality system to conform to their Self. This makes them oddly somewhat like tar souls, but unlike tar souls, they still need the filter of Morality to justify their Self.
Ambitrinsic pure souls are more balanced between the two forces, able to alter both their morality system and their sense of self in a compromise to bring them both in alignment with eachother.
Neutrinsic pure souls, contrary to the other subtypes, have a mismatching morality system and sense of self, but unlike the grime soul, are able to comfortably not acknowledge the contradiction between their Morality and Self, being able to act from their Morality when needed or desired and from their Self when needed or desired. Their refinement lies in their ability to
Immoral. Grime souls have a conflicting morality system and sense of self that are misaligned.
Amoral. Tar souls lack a morality system, instead being guided purely through their sense of self. Raw power.
