Themes

Customise proto’s color scheme via the /theme command or settings.json.

Change theme

/theme

Use arrow keys to select from the list. The selection is saved automatically.

Built-in themes

Dark: ANSI, Atom One, Ayu, Default, Dracula, GitHub

Light: ANSI Light, Ayu Light, Default Light, GitHub Light, Google Code, Xcode

Set via settings

{
  "ui": {
    "theme": "Dracula"
  }
}

[!note] If theme is set in settings.json, the /theme command won’t override it until you remove the setting from the file.

Custom themes

Define a custom theme in settings.json:

{
  "ui": {
    "customThemes": {
      "MyTheme": {
        "name": "MyTheme",
        "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"
      }
    },
    "theme": "MyTheme"
  }
}

Required color keys: Background, Foreground, LightBlue, AccentBlue, AccentPurple, AccentCyan, AccentGreen, AccentYellow, AccentRed, Comment, Gray.

Optional: DiffAdded, DiffRemoved, DiffModified, GradientColors.

Values accept hex codes (#FF0000) or CSS color names (coral, teal).

Load a theme from a file

{
  "ui": {
    "theme": "/path/to/my-theme.json"
  }
}

The JSON file must follow the same structure as an inline custom theme. For security, proto only loads theme files within your home directory.

Custom themes via settings scope

Custom themes can be set at user, project, or system scope and follow the same configuration precedence as other settings.
