Colour-coding is the idea of designating certain cleaning tools and processes by consistent colour schemes.
Its purpose is the segregation of equipment, materials and procedures as a means of preventing cross-infection and cross-contamination in the home and the workplace.
The colours used must remain consistent for their tasks, and the fewer colours used, the better. 

• Red - most often used in high-sanitary (high risk for the spread of infection) applications or in restroom cleaning, such as with toilets and urinals
• Yellow - for sinks, counters and washroom surfaces; also used for specialty cleaning (counters, mirrors), gym areas and metal works
• Blue - in lower-risk areas of a building, such as desktops, ledges, window cleaning and high and low dusting
• Green - used in food-processing and food-serving areas, as well as bar areas
