The most recognizable part of the standard is its codification of colors used on control panels and equipment. The standard works primarily with seven colors for indicating devices and actuators (controls like buttons).
The standard read like a hymn for clarity. Colours and shapes, meanings and priorities: red for danger, yellow for caution, green for safe; a triangle for warning, a circle for normal; a buzzer for attention, a steady tone for confirmation. It wasn’t just aesthetics. It was survival distilled into guidelines—how a single symbol could shorten reaction times in a control room, how standardized signals could prevent a cascade of errors when languages and cultures mixed.
Flashing is used to indicate that immediate attention is required, often distinguishing a "warning" from a "danger" state.
The primary objective of this standard is to establish a uniform system of colors, shapes, and sounds to represent specific machine states. By standardizing these elements, the IEC aims to: iec 60073 pdf

Indicates a high-priority, urgent emergency state (red). 3. Acoustic Coding
The most heavily referenced section of any download is the standardized color coding matrix. Colors are assigned specific meanings based on whether they represent a machine status (indicator) or an operator action (actuator). 1.

He was a standards engineer by trade—soft-spoken, wearied by committee meetings and the slow churn of consensus. His name was Marco. For years he’d watched operators misread indicator lights, technicians misinterpret instrument panels, and managers shrug at costly mistakes. One rainy evening, with the plant’s generators thudding like a distant heartbeat, Marco pulled IEC 60073 from the shelf and opened the world it described: a system of tactile, visual, and auditory symbols—an agreed grammar for how devices speak to people.
No specific meaning (used for confirmation or neutral status). 2. Temporal Coding (Flashing Indicators)

Ever looked at a machine control panel and wondered: Why is the emergency stop always red? Why is the start button green?
