To be a PURE color, you must have ONE way of approaching your trauma, along with a balance between OBSESSION and STARTING OVER & MOVING ON.
Here are the pure colors:
Orange = Whiners who use their trauma for attention
Green = They know how it is, they know it's impossible to change but they still wish that it could be changed.
Blue = Face and confront their traumas
Purple = Relish/live in fear of their traumas
Red = They wish to run away or avoid their trauma
Yellow = Joke about or divert attention from their trauma
Black = Obsess over their trauma
White = Just want to let go and start over
Metal = A repressed trauma
To obtain X ability, your character must have the DESIRE for said ability and must respond to dealing with their trauma in said way, the avatar after all (both ability and body) is made in some way to cope with the trauma that they have.
