What color is used to identify common equipment?

Color coding in cabling work is a visual way to quickly identify what kind of equipment you’re looking at. In BICSI copper practice standards, violet (purple) is the color designated for common equipment. This means items that serve multiple circuits or services — like distribution frames, cross-connects, or central racks that multiple cables connect to — are marked violet to signal they are shared or generic rather than tied to a single user or function. Using this color consistently helps technicians avoid misinterpreting equipment and makes installation, testing, and maintenance smoother. Other colors are reserved for other designations, so violet/purple is specifically the cue for common equipment.
