# Themes

Qwen Code supports a variety of themes to customize its color scheme and appearance. You can change the theme to suit your preferences via the `/theme` command or `"theme":` configuration setting.

## Available Themes

Qwen Code comes with a selection of pre-defined themes, which you can list using the `/theme` command within the CLI:

- **Dark Themes:**
  - `ANSI`
  - `Atom One`
  - `Ayu`
  - `Default`
  - `Dracula`
  - `GitHub`
- **Light Themes:**
  - `ANSI Light`
  - `Ayu Light`
  - `Default Light`
  - `GitHub Light`
  - `Google Code`
  - `Xcode`

### Changing Themes

1.  Enter `/theme` into Qwen Code.
2.  A dialog or selection prompt appears, listing the available themes.
3.  Using the arrow keys, select a theme. Some interfaces might offer a live preview or highlight as you select.
4.  Confirm your selection to apply the theme.

**Note:** If a theme is defined in your `settings.json` file (either by name or by a file path), you must remove the `"theme"` setting from the file before you can change the theme using the `/theme` command.

### Theme Persistence

Selected themes are saved in Qwen Code's [configuration](../configuration/settings) so your preference is remembered across sessions.

## Custom Color Themes

Qwen Code allows you to create your own custom color themes by specifying them in your `settings.json` file. This gives you full control over the color palette used in the CLI.

### How to Define a Custom Theme

Add a `customThemes` block to your user, project, or system `settings.json` file. Each custom theme is defined as an object with a unique name and a set of color keys. For example:

```json
{
  "ui": {
    "customThemes": {
      "MyCustomTheme": {
        "name": "MyCustomTheme",
        "type": "custom",
        "Background": "#181818",
        ...
      }
    }
  }
}
```

**Color keys:**

- `Background`
- `Foreground`
- `LightBlue`
- `AccentBlue`
- `AccentPurple`
- `AccentCyan`
- `AccentGreen`
- `AccentYellow`
- `AccentRed`
- `Comment`
- `Gray`
- `DiffAdded` (optional, for added lines in diffs)
- `DiffRemoved` (optional, for removed lines in diffs)
- `DiffModified` (optional, for modified lines in diffs)

**Required Properties:**

- `name` (must match the key in the `customThemes` object and be a string)
- `type` (must be the string `"custom"`)
- `Background`
- `Foreground`
- `LightBlue`
- `AccentBlue`
- `AccentPurple`
- `AccentCyan`
- `AccentGreen`
- `AccentYellow`
- `AccentRed`
- `Comment`
- `Gray`

You can use either hex codes (e.g., `#FF0000`) **or** standard CSS color names (e.g., `coral`, `teal`, `blue`) for any color value. See [CSS color names](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value#color_keywords) for a full list of supported names.

You can define multiple custom themes by adding more entries to the `customThemes` object.

### Loading Themes from a File

In addition to defining custom themes in `settings.json`, you can also load a theme directly from a JSON file by specifying the file path in your `settings.json`. This is useful for sharing themes or keeping them separate from your main configuration.

To load a theme from a file, set the `theme` property in your `settings.json` to the path of your theme file:

```json
{
  "ui": {
    "theme": "/path/to/your/theme.json"
  }
}
```

The theme file must be a valid JSON file that follows the same structure as a custom theme defined in `settings.json`.

**Example `my-theme.json`:**

```json
{
  "name": "My File Theme",
  "type": "custom",
  "Background": "#282A36",
  "Foreground": "#F8F8F2",
  "LightBlue": "#82AAFF",
  "AccentBlue": "#61AFEF",
  "AccentPurple": "#BD93F9",
  "AccentCyan": "#8BE9FD",
  "AccentGreen": "#50FA7B",
  "AccentYellow": "#F1FA8C",
  "AccentRed": "#FF5555",
  "Comment": "#6272A4",
  "Gray": "#ABB2BF",
  "DiffAdded": "#A6E3A1",
  "DiffRemoved": "#F38BA8",
  "DiffModified": "#89B4FA",
  "GradientColors": ["#4796E4", "#847ACE", "#C3677F"]
}
```

**Security Note:** For your safety, Gemini CLI will only load theme files that are located within your home directory. If you attempt to load a theme from outside your home directory, a warning will be displayed and the theme will not be loaded. This is to prevent loading potentially malicious theme files from untrusted sources.

### Example Custom Theme

### Using Your Custom Theme

- Select your custom theme using the `/theme` command in Qwen Code. Your custom theme will appear in the theme selection dialog.
- Or, set it as the default by adding `"theme": "MyCustomTheme"` to the `ui` object in your `settings.json`.
- Custom themes can be set at the user, project, or system level, and follow the same [configuration precedence](../configuration/settings) as other settings.
