A foreign equipment color scheme refers to the standardized use of color coding or color patterns on machinery, tools, or devices in various industries. These colors are typically used for safety, identification, or organization purposes. In industrial settings, different colors may indicate different levels of risk, types of equipment, or operational status. For example, red may signify 'stop' or 'hot', while yellow might indicate 'caution'. Color schemes are also used in healthcare and other industries for patient safety and staff training.
