UiO's colours and accessability requirements

Overview of approved colour combinations within UiO's colour palette.

The University of Oslo must meet accessibility requirements. When we choose colours for text and backgrounds on different kinds of graphic materials, we have to make sure that the resulting colour combinations have a sufficiently high contrast ratio.

To make this as easy as possible, we have tested all colour combinations within UiO's colour palette and documented which of them meet the contrast accessibility requirements.
