GREEN means Go: You’re feeling OK. Just keep using your preventive (anti-inflammatory) medicine.
YELLOW means Be Careful: You’re having some symptoms. It’s time to use your quick-relief (short-acting bronchodilator) medicine, in addition to the preventive medicine.
RED means STOP: Your symptoms are serious. You need to get help from a doctor!
