Supranational organisations

Some noted supranational organisations like the United Nations and the European Union have their own colours as part of their branding and marketing. They are usually taken from the organisation's flag. Although they do not have national sporting teams, the colours can be used for anything connected to the organisation, like associated bodies.

Examples of use of these colours

• United Nations: the recognisable blue helmets of the peacekeeping operations and the flags of associated UN agencies like the World Health Organization, with the UN's light blue and white.
• European Union: the blue and yellow of the EU flag; uses include the blue European Health Insurance Card and the Blue Card for skilled immigration.
