Color code

A colour code is a system for displaying information by using different colours. Colour codes are often difficult or impossible for blind and colour blind people to understand.

Examples of colour codes:

Bottled gases
Electrical wiring
Electronic colour code
Web colours for HTML colour codes
25-pair colour code
Fire extinguishers
Hanky code
Jumper cables
Traffic lights
Navigation lights, sea marks and characteristic lights
Ribbon colours see: Category:Ribbon symbolism
U.S. Department of Homeland Security's Advisory System
Utility colour codes

The Color Code is also the title of a book (References, Joseph et al., 2002) combined with a nutritional practice by the same name in another book publication (Heber, 2001). The Color Code combines food science, medical knowledge and nutritional practices to encourage consumer intake of colourful plant foods for achieving optimal health.
