# Customizing Theme Settings

**Thinfinity® Workspace Web Manager** provides three preset themes to choose from: Light theme (default), Dark, and Blue.

Additionally, the Theme Customization **Thinfinity® Workspace API** provides companies with the ability to implement their own branding through the customization of some branding aspects such as the color palette and logo, thereby enabling the creation of personalized themes according to their identity.

The customization is accomplished using a set of two files:

* [A JSON configuration file](https://thinfinity-workspace-v8-docs.cybelesoft.com/customizing-the-user-experience/customizing-theme-settings/json-configuration-file) that defines what and how to configure it.
* [A CSS file based on an API](https://thinfinity-workspace-v8-docs.cybelesoft.com/customizing-the-user-experience/customizing-theme-settings/customizing-theme-styles) of styles that are applied to each of the pages and sections of **Thinfinity Workspace**.

The API defines:

* CSS variables for:
  * The color palette to apply to the interface.
  * Other interface elements such as logo images and background.
* CSS style overrides.
