Main colour

Karolinska Institutet’s main colour is plum. The KI plum is an important element of our brand and our graphic identity. Therefore, wherever possible, it must be used in all communication for which KI is the sender.

Something to think about!

KI’s graphic rules also applies if the sender is a department, unit or section at KI, for example if you create a poster for a lecture you are organising.

How to use the main colour plum

Whenever possible, the most prominent colour must be plum. You can use plum as the background on a publisher area, colour palettes, and as text colour.

Two examples of how the complementary colour cyclamen can be used.

How to use the complementary colour cyclamen

Use cyclamen as a complement to plum. For example, on smaller, or parts of, graphic elements, lines, smaller figures or colour palettes. The combination of plum and cyclamen is unusual and is therefore an effective recognition trigger.

How to use the complementary colour grey

The profile colour grey is a colour that can easily be combined with both the main colour and with cyclamen. It is a neutral colour that complements the stronger colours well, and can be used in all designs.

Use it in graphic elements, figures, lines or colour plates.

Use of colours other than plum, cyclamen and grey?

You have access to an infinite number of supplementary colours and you can use any colour you wish; however, plum must be the main colour and the most prominent.

For example, use them in smaller elements in your layout together with the publisher area in plum.

Ceremonial colours

The ceremonial colours gold and silver are used for academic ceremonies and for other important occasions. The Communications and Public Relations Office must approve use of ceremonial colours.
