What color is NOT one of the standard ACP colors?

In the context of cockpit displays and controls, specific colors are used to convey different meanings based on established color codes for aviation. Blue is typically associated with operational or normal functions, red signifies warnings or critical situations requiring immediate attention, and amber is often used for caution, indicating that there may be a potential issue that needs to be monitored but is not immediately critical.

Purple, however, does not correspond to any standard aviation color code for aircraft systems or alerts. While some systems may use purple for specific indications, it is not recognized as one of the standard colors used in the context of Aircraft Control Panels (ACP) for operational status or reporting. Understanding this distinction is crucial, as color recognition plays a vital role in situational awareness and responding appropriately to various cockpit alerts and indications.
