# UI Theme

The **UI Theme** tab in Platform Settings allows administrators to customize the **look and feel of the Nexus Management Portal**. This feature is useful for organizations that want to white-label Nexus with their own branding, ensuring a consistent visual identity across internal tools and platforms.

These settings require the [Administrator Role](/platform-architecture/security-architecture/user-roles-and-permissions.md) to access and modify.

* **Custom Colors**\
  Administrators can configure the primary, secondary, header, and label colors of the Nexus interface. By aligning these with company brand guidelines, the Management Portal can better reflect the organization’s identity.
* **Custom Logo**\
  Administrators can upload a company logo that replaces the default Nexus logo in the **top-left corner** of the portal.
  * The uploaded logo must be **≤ 1 MB**.
  * Supported formats: `.png`, `.jpg`, `.svg`.
* **Save and Refresh**\
  Once changes to colors or logos have been made, click **Save**. The Management Portal will automatically **reload** in the browser, applying the new theme.

* After saving changes, it may be necessary to **clear the browser cache** for the new theme and logo to take full effect.
* This ensures that any cached styling files or images from the previous theme do not override the new configuration.
  {% endhint %}

### Resetting to Default

If needed, administrators can restore the **default Nexus colors and logo** by clicking the **Reset Default Settings** button. This action will reset the Management Portal theme back to its original state.
