Couleur (from French, in English Colour, or in the United States Color) is the expression used in Central European Studentenverbindungen for the various headgear and distinctive ribbons worn by members of these student societies.
There are three classes of such student societies:
- Societies with no colours (so called schwarz, in English black)
- Societies with colours but wearing no ribbon, no cap etc. They wear their colours e.g. in their coat of arms or as Zipfel.
- Societies with colours and wearing a ribbon, a cap etc.
