Yes, indirectly. Virtual buttons on an HMI should follow the same color meanings. However, tactile coding does not apply to touchscreens.

Indicators communicate the status of a system or machine. IEC 60073 outlines strict meanings for colors used in pilot lights, tower lights, and HMI (Human-Machine Interface) screens:

To ensure compliance with IEC 60073, consider the following best practices:

A standard that specifies coding principles for visual indicators and actuators to ensure machine safety. iec 60073 pdf

Avoid "free PDF" sites from Russia/China – they are often scanned from the 1996 edition which is obsolete.

When visual signals are insufficient, acoustic signals provide critical alerts through pure tones, specific frequencies, or spoken messages. These are categorized by urgency and should be designed to be distinguishable from ambient factory noise. IEC 60073:2002

IEC 60073 does not exist in a vacuum. It works in tandem with other critical industrial standards, such as: Safety of machinery (electrical equipment). Indicators communicate the status of a system or machine

Color is the most critical element of visual coding. IEC 60073 assigns specific, non-negotiable meanings to colors used on indicator lights and actuators (push-buttons). Meaning for Indicator Lights Meaning for Actuators (Buttons) Danger / Emergency Act to respond to danger (Stop) Emergency stop, fire alarm Yellow Abnormal / Warning Act to suppress abnormality Overload warning, reset Green Safe / Normal Act to initiate safe conditions Start machine, normal flow Blue Mandatory action Act requiring mandatory intervention Fill fluid, check gauge White/Gray Neutral / No specific meaning General initiate/stop functions General power on, cycle start 2.
