Color coding in production
Color coding in production is a method of transmitting information through colors, without the need for additional written explanations, part of the visual management of Lean production. The production environment being very dynamic, where quality, efficiency and clarity are essential, color and their code become a reliable support through a universal language, similar to traffic lights, simple and efficient.
The color coding system must be standardized, easy to understand and consistent. Here are some recommendations for basic rules:
- the same colors must be used everywhere, the code must be universal in the factory
- where necessary, a legend with the meaning of the colors can be displayed, help for visitors or new employees
- the colors must be intuitive, general, also encountered in everyday life
- they must be visible and clear
- training employees to know the meaning and thus comply with the standard
- periodic maintenance of markings, labels, areas
An example of a standardized color code in production:
- Green – means good, functional, work areas ok, products and parts compliant
- Red – signals a problem, defect, prohibited areas, rejected and/or quarantined products, unplanned or emergency stop
- Yellow – is the color of warning, risk areas, intervention, parts awaiting decision
- Black – delimitation of work areas, equipment, contours shelves, tools
- Blue – logistics routes, internal factory material transport, temporary storage
Thus the color code is the non-verbal language of order and clarity, a fast and efficient method for standardization and discipline in production areas.
