What are the color codes of awareness?

Colonel Jeff Cooper brought us the color codes of awareness to help civilians understand more about situational awareness. Cooper assigned a color to the various stages of awareness and lack of awareness. If we are in condition white (unaware and unengaged) and we are attacked we have no other place to go then conditional red (defending our life) where we must defend ourselves with force. However, if we are in condition yellow (aware) and we are concerned we can move up to condition orange (heightened awareness, or active) thus avoiding condition red. In short, the more we are aware of our surroundings the less often we are forced to use lethal force.
