Introduction
Last updated: 8 November 2024, 13:59 by Siobhan Rawson
Nordea Design System colour system offers a wide range colours to create meaningful user experiences. Colour provides visual balance and harmony across digital services. It enhances brand familiarity and communicates hierarchy.
Currently our library consists of our Nordea blue digital palette and a palette for data visual insights.
Principles
Colour is important in perception and understanding of a product. The Nordea blue digital palette derives from the Nordea brand palette. Blue hues are at the centre of the Nordea colour palette, complemented with accent colours and neutral grays.
Our data visualisations and insights palette are for insights, graphs and analytical purposes. They are composed of a more vivid colour scheme to ensure they are coherent when used in stroke formats
Clear purpose
Nordea blue digital palette
Blues, secondary grays and special accent colours make up the Nordea colour palette.
- Use blue colours for navigational and interactive elements
- Use grayscale colours for text
- Use accent colours to communicate special states such as alerts and errors
Data visualisation and insights
- Use the 5 primary colours before adding in secondary where possible
- For insight categorisation use the corresponding colour assigned to in Expenses categories ( see Figma file)
Accessible
At Nordea, we aim to meet the AA grade compliance of Web Content Accessibility Guidelines (WCAG) 2.1.
- All colour combinations must provide enough contrast¹. Some users with such visual impairments as colour blindness may perceive colour combinations differently²
- Use colours from the Light theme colour palette when designing for the default colour mode
- Use colours from the Dark mode colour palette when designing for Dark mode
- For data visualisation and insights – you the first 5 primary colours (Vivid blue, Blau, Rose, Apricot, Dark mint) to ensure clear contrast within graphs, charts etc. If needed secondary colours can then be used
We also have a table in which our nordea blue digital palette has been checked for contrast against each colour and their ratings given in compliance to WCAG 2.1 guidelines. Go to the Foundation library figma file to check
Familiar
The colour palette of our digital services reinforces the Nordea brand.
Colour palette
Nordea Design System supports two colour modes.
- Light theme is the default colour palette
- Dark mode is the secondary colour palette. It reduces power usage of devices and increase visibility of content in low-light environments

Colour balance
Besides typography and layout, colours can create a sense of hierarchy within a page. Application of high-contrast colour combinations ensures legibility of content.
Nordea blues and deep blues provide a sense of familiarity. They also highlight interactive elements against a grayscale background. Reds, yellows, greens and lighter blues communicate system statuses (such as error or success states).
Colour usage
Informational accent
Use light blue colours to highlight tips and informational content.
Critical error accent
Use red colours to communicate critical errors that require user atterntion.
Warning accent
Use yellow colours to display service errors, authentication errors and warnings.
