Magical fighting colors for masters?

[Isalinnea]

You know that special fighting way you learn in china? Good. Then you also know that when your sim is a master of it you can see some magical colors when they fight with other sims? Good. Now to my question. What decides which color your sim gets? Can you change it? Please help me! I'd really like my sim to fight with red color instead of yellow. D=

Answer: It's decided by an arbitrary invisible value, so it's basically random, but deterministic across a given implementation of a character. No, you can't change it. I could change how this color is determined, but otherwise, it's chosen between a set of 5 possible colors.
