Themes

OpenCode supports most common terminal themes and you can create your own custom theme.

Built-in themes

The following predefined themes are available:

• opencode
• catppuccin
• dracula
• flexoki
• gruvbox
• monokai
• onedark
• tokyonight
• tron
• custom

Where opencode is the default theme and custom let’s you define your own theme.

Setting a theme

You can set your theme in your OpenCode config.

.opencode.json

{
  "tui": {
    "theme": "monokai"
  }
}

Create a theme

You can create your own custom theme by setting the theme: custom and providing color definitions through the customTheme.

.opencode.json

{
  "tui": {
    "theme": "custom",
    "customTheme": {
      "primary": "#ffcc00",
      "secondary": "#00ccff",
      "accent": { "dark": "#aa00ff", "light": "#ddccff" },
      "error": "#ff0000"
    }
  }
}

Color keys

You can define any of the following color keys in your customTheme.

Type	Color keys
Base colors	primary, secondary, accent
Status colors	error, warning, success, info
Text colors	text, textMuted, textEmphasized
Background colors	background, backgroundSecondary, backgroundDarker
Border colors	borderNormal, borderFocused, borderDim
Diff view colors	diffAdded, diffRemoved, diffContext, etc.

You don’t need to define all the color keys. Any undefined colors will fall back to the default opencode theme colors.

Color definitions

Color keys can take:

1. Hex string: A single hex color string, like "#aabbcc", that’ll be used for both light and dark terminal backgrounds.

2. Light and dark colors: An object with dark and light hex colors that’ll be set based on the terminal’s background.
