If there is an infected animal in the Red stable, you do not want the disease to spread to the Yellow stable. Similarly, adult animals will have build up immunity against certain pathogens in their environment, but you will want to prevent the spread of these pathogens to the area where young animals are held, as these pathogens can still have serious consequences for young animals.
Therefor it is important to avoid the transmission of germs between animals. A major threat to this transmission is movement of personnel and the tools, equipment and attributes they bring with them. With a colour system, these tools and attributes can be kept separate by animal group or department. This means that boots, overalls, shovels, brooms and floor pullers are in the same colour of the stable they are used in.
A colour system is very easy to implement. This starts with using the appropriate coloured tools, such as shovels, brooms, floor pullers, coveralls and footwear, specifically assigned to each department.
To make the separation between departments clear, you can choose to apply colour coating or place color-coded signs. This way the separation is not only visible in the attributes but also visually in the barn.

By keeping all tools, clothes and equipment separated per barn you significantly reduce the risk of pathogens spreading from one area to the next. The dedicated colours make it easy to identify a misplaced item or to identify workers that did not follow protocols.
Moreover a colour system helps to create a culture of biosecurity by making the system highly visible, raising awareness about biosecurity with workers.
