# WUI settings

The **WUI Settings** section of Data Watcher comes with the possibility to set a **header** that will appear on all pages. Here below, you can find an example of the header in the **Dataflow Models** section.

You can customize the text that will appear in the header, as well as the color of the text and background.

Let's see how to do it.

First head over to the **Setup** → **WUI Settings** section. Here, you will find a **Show** toggle that you can use to make the header visible or invisible.

When the **Show** toggle is set to ON, the following options will appear:

* **Environment**: this field contains the text that will appear in the header. By default, primeur-datawatcher appears but you can edit it as needed.&#x20;
* **Colors**: here you can set the color of the text and the color of the background using either the #HEX format (e.g. #00000, #FF000) or the HTML color name (e.g. black, red).

When you have defined the style of your header click **Save** or select **Reset** to undo.
