Design tokens

Design tokens are NewsKit’s design decisions. They maintain a scalable and consistent experience for users.


Design tokens are named entities that store visual and functional information. They take the place of hardcoded values, such as hex values for colour or pixel values for spacing.

Literal vs contextual tokens

Literal tokens

Literal tokens add a layer of abstraction to hardcoded values. Rather than reference a colour directly (e.g.#5E44E4) you can ‘tokenise’ it to purple050.

Now, if you need to change the shade of purple, rather than finding everywhere you’ve used the hex code, you can update it all in one place by changing the value of purple050.

Contextual tokens

Contextual tokens add a further layer of abstraction and assign the token a specific purpose. In the example above, you can give purple050 token context - say, it should be used in typography as the brand colour - by assigning it the inkBrand token.

Contextual tokens let you do things like customise the way components look product-wide. When deciding between a contextual or literal token, consider: would you want the value you’re using to change if you changed the theme? If yes, use a contextual token.

Naming convention

Tokens follow a camelCase naming convention (e.g. lineHeight) to ensure they’re clear, flexible and extensible.

Where the token maps to a numerical series, three digits (in increments of 10) are added as a suffix. Tokens follow the naming convention: {Property}{Series}

For example:



When constructing components, you can group design tokens into presets. This creates a simple way to customise particular aspects of a component.
