Toolpad Studio allows you to add your custom theme to your app, or customize individual component styles.

Adding a global theme

  1. To change the application theme, go to the Theme tab in the inspector panel.

  2. In the theme options you can:

    • change your UI to light or dark mode.
    • set primary and secondary colors for your UI, from a predefined list of colors.
  3. The theme used in a project is configured by an auto-generated theme.yml file inside the toolpad folder. The file schema documentation contains detailed information on the supported options.


In order to provide a customised styling to the components used in your pages, you can use style overrides via the sx prop in the Inspector.
