Color Coordination

Imagine a world where everyone has a power. Said power is determined at the age of five by a mutagenic chemical used in their hair. The chemical changes their hair color based on their DNA structure. Once that's figured out, they're put into separate camps. Red hairs have brute strength, and are put into the Army. Green hairs can control plants and animals. They get farming. Blue and white hairs are geniuses, and blues get Navy, whites get Air Force. Gold have a super charisma, and become diplomats. Black hairs have super speed and animalistic instincts. They become assassins.

But what about the ones with multi-colored hair?
