The Environmental Protection Agency (EPA) has assigned a specific color to each Air Quality Index (AQI) category to make it easier for people to understand quickly whether air pollution is reaching unhealthy levels in their communities. For example, the color orange means that conditions are "unhealthy for sensitive groups," while red means that conditions may be "unhealthy for everyone," and so on.
