: Encouraging the use of more than one sensory channel (e.g., visual and acoustic) to convey critical information. Core Coding Principles
The standard assigns specific meanings to visual and physical attributes. The primary coding methods include colors, shapes, and acoustic signals, with color being the most widely recognized. 1. Color Coding for Indicators (Lights and Screens) iec 60073 pdf

The you are designing (e.g., physical control panels, HMI touchscreens) By establishing a uniform language for indicator lights,
The primary objective of this standard is to ensure safety and efficiency by standardizing the visual, acoustic, and tactile signals used on control panels and machinery. By establishing a uniform language for indicator lights, pushbuttons, and displays, IEC 60073 minimizes the risk of operator error across different manufacturers and countries. Core Coding Principles
