# Chat Theme

Navigate to [Chat > Theme](https://app.spara.co/settings/chat/theme) in the Spara platform to access these settings. The **Live preview** at the bottom of the page reflects any changes immediately, so this can be used to test and verify changes. Once you are happy with the preview, select the save changes button to apply them to your website.

#### Navigator / Fullscreen Settings

Navigator and Fullscreen settings are linked, so any changes you make in Navigator will reflect in Fullscreen as well. Outside of the chat theme, to edit the suggested responses and chat mode, refer to [Previews](/agents/channels/chat/spara-navigator.md#previews), this allows you to define how Spara navigator looks before a visitor engages.

* **Privacy message:** Shown at the bottom of every chat. Supports Markdown links - e.g. `[Privacy Policy](https://yoursite.com/privacy)`
* **Privacy text color:** Customize the text color of the privacy message. Useful when using a dark chat background where the default gray would be hard to read. Falls back to neutral gray when unset.
* **Chat Colors:** Customize the color of every visual element in the chat window - the top bar, chat background, send / media buttons, bot and lead message bubbles, text colors, link colors, and suggested responses color. Each field allows you to select a color visually or enter a hex color code.
* **Chat Channel Avatar:** Change the avatar or name. The avatar must be a 200x200 px image.

#### Smartbar Settings

* **Title & Input placeholder:** This is the text the lead sees before they start typing
* **Placeholder media title & CTA:** Once a lead clicks into the Smartbar, on the left side the you have the option to add a placeholder media CTA which links to a media asset.
* **Suggested responses:** Enter one response per line. These appear as clickable bubbles below the bar the lead can start typing.
* **Appearance:** Customize the primary color, background color, text color, padding, and an optional background image.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.spara.com/agents/channels/chat/chat-theme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
