UM’s colour gamut is based on four basic colours: dark blue, white, orange-red and light blue. The four basic colours can be extended with target group colours in media intended for specific target groups. 


Almost all communication media feature the four basic colours, whose mutual proportions can differ depending on their aim. The main colours, dark blue and white, will dominate in all corporate media.

The accent colours, orange-red and light blue, play a supporting and more illustrative role.

  • largely white designs are usually more suitable for business media, where excessive use of colour detracts from functionality (e.g., reports, digital newsletters)
  • predominantly dark blue designs with accent colours are better suited to more stylish, image-strengthening media (e.g., invitations, annual reports)

The following image shows the target group colours (bachelor's orange and master's red) applied within the context of the four basic colours:


Black and white

In black and white media, the logo must always be black on a white background. The other colours cannot be translated into black and white versions; in addition, existing full-colour media cannot simply be converted into tone values, as the original colours may generate an entirely different picture. Thus, always design black and white media separately, even if a full-colour version is already available.

Monochrome and duotone

Monochrome (one-colour) media must always be in UM’s main colour, dark blue (PMS 295). These are subject to the same instructions as black and white communications.

Duotone communications must always be in black and dark blue, with the logo in dark blue.

Digital applications

Digital applications use the same four main colours as printed materials.

Colour and contrast: web guidelines

The public website of Maastricht University must comply with AAA guidelines for web accessibility (Dutch only). This means, among other things, that the contrasts between the use of text and coloured backgrounds (including white) must be sufficient. You can check this with this tool.

There are rules for text larger than 18px and text smaller than 18 px.

These rules are very strict and are difficult to apply within the colour palette of the UM Branding. Though it is very difficult to meet all web guidelines, your content must still be as accessible as possible. The web guidelines for colour are all about contrast. Use colour and contrast to ensure that users understand the navigation, possible actions, and that the content is easily readable. This involves both colours and text, in making them as clear as possible.
