# Set theme

The Set theme action node changes the theme used by an app, instantly altering the color palette and typography. To set a theme, it must be first created under [Themes](/reference/resources/themes.md).

## Usage

Common use cases for this action node include switching between light mode and dark mode, or enabling a customer theme that features their brand colours. It is possible to store a theme as an object class property, for example as part of a customer object or in an object attached to a user, and enable that theme using Set theme.

For a step-by-step guide to adding a theme switcher to an app, see [Change the active theme](/how-to/themes-and-styling/change-the-active-theme.md).
