The four warning colors typically refer to a system used in various contexts, such as weather alerts or safety signage. For instance, in the context of weather warnings, colors like blue, yellow, orange, and red often represent increasing levels of severity: blue for advisory, yellow for watch, orange for warning, and red for emergency. Each color signifies a different level of urgency and potential risk, helping individuals respond appropriately to the situation.
