The 12 Colors of Combat is a new approach to martial arts and self-defense. It takes a functional rather than a stylistic approach to personal combat. The concept of negative space is introduced and the dodecahedron is the model used to for a structural reference. This book and the other books written by Simmons will improve any practitioner's ability by at least 500%, independent of their "style" of combat. The 12 Colors of Combat is meant to be a reference work for years to come along with the other books in the Simmons Wu-Chi Combat Series.
