The Cooper color code, developed by Jeff Cooper, names states of mental alertness: White is unaware, Yellow is relaxed alert, Orange is a specific alert on something you have noticed, and Red is acting on a plan. Make Yellow your default whenever you are awake and outside, move to Orange when something triggers you, and never stay in White when you are alone or outside. The colors describe your state of mind, not how dangerous the world is.
Part of Situational Awareness
Jeff Cooper’s colour code names levels of mental alertness, from White (unaware) to Red (acting on a plan). The parent article describes it as originally developed for combat awareness, and it is applied here to avoidance and withdrawal.
The Colors Describe Your Mind, Not the Threat
The code is attributed to Jeff Cooper, who developed it for personal-defence awareness. It is a doctrine of attention, not data about danger. The parent article uses four states.
- White — Unaware. Relaxed and not paying attention. Acceptable only inside a secure shelter with others standing watch. Never be in White when alone or outside.
- Yellow — Relaxed alert. Your default whenever you are awake. You are not expecting a specific threat, but you are scanning, listening and processing, so you notice the bird that stopped singing or the shadow that moved.
- Orange — Specific alert. Something has triggered your attention. You have identified a potential threat and are evaluating it, running scenarios, identifying your exits and cover.
- Red — Action. A threat is confirmed and you are carrying out your plan.
Some later instructors have added further levels beyond these four. This page uses only the four above.
In a Defensive Plan, Red Means Leave, Hide or Move
The parent article lists evacuation, hiding and confrontation as the possible Red responses. For this corpus, the plan you make in Orange should put withdrawal and concealment first, with avoidance as the objective. Decide that in advance, in Yellow, when you can think.
What You Need
- A default to hold — Yellow.
- Named triggers — what takes you from Yellow to Orange. See Danger Indicators.
- A planned response for Red — decided beforehand. See Escape Routes.
Method: Moving Between Colors
Step 1: Rest in Yellow Scan, listen and notice, without strain. The goal is to spend most of your time here.
Step 2: Shift to Orange when triggered A sign from the danger list moves you up. Stop, face the sign, and note your exits and cover.
Step 3: Run the scenarios Ask: if that person does X, I will do Y. Pick the quietest answer, usually to move away.
Step 4: Go to Red only on confirmation If the threat is confirmed, carry out the plan you chose in Orange.
Step 5: Come back down When the sign proves harmless or you are clear, return to Yellow. Staying in Orange for hours degrades judgement.
Common Mistakes
- Living in Orange — you cannot hold it for hours without degrading. See Fatigue Management.
- Dropping to White to relax — rest in a secure place with a watch posted instead.
- Treating the colors as a script — they are labels for your state, not a replacement for judgement.
