Themes

TerminaI 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

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

Dark themes:
- ANSI
- Atom One
- Ayu
- Default
- Dracula
- GitHub
Light themes:
- ANSI Light
- Ayu Light
- Default Light
- GitHub Light
- Google Code
- Xcode

Changing themes

Enter /theme into TerminaI.
A dialog or selection prompt appears, listing the available themes.
Using the arrow keys, select a theme. Some interfaces might offer a live preview or highlight as you select.
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 TerminaI’s configuration so your preference is remembered across sessions.

Custom color themes

TerminaI 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:

{  "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)

You can also override individual UI text roles by adding a nested text object. This object supports the keys primary, secondary, link, accent, and response. When text.response is provided it takes precedence over text.primary for rendering model responses in chat.

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 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:

{  "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:

{  "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, TerminaI 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.

Using your custom theme

Select your custom theme using the /theme command in TerminaI. 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 as other settings.
