 title: Themes

+With opencode you can select from one of several built-in themes, use a theme that adapts to your terminal theme, or define your own custom theme.
+
+By default, opencode uses our own `opencode` theme.

+## Built-in themes
+
+opencode comes with several built-in themes.
+
+| Name | Description |
+| --- | --- |
+| `system` | Adapts to your terminal's background color |
+| `tokyonight` | Based on the Tokyonight theme |
+| `everforest` | Based on the Everforest theme |
+| `ayu` | Based on the Ayu dark theme |
+| `catppuccin` | Based on the Catppuccin theme |
+| `gruvbox` | Based on the Gruvbox theme |
+| `kanagawa` | Based on the Kanagawa theme |
+| `nord` | Based on the Nord theme |
+| `matrix` | Hacker-style green on black theme |
+| `one-dark` | Based on the Atom One Dark theme |
+
+And more, we are constantly adding new themes.

+
+## System theme
+
+The `system` theme is designed to automatically adapt to your terminal's color scheme. Unlike traditional themes that use fixed colors, the _system_ theme:
+
+- **Generates gray scale**: Creates a custom gray scale based on your terminal's background color, ensuring optimal contrast.
+- **Uses ANSI colors**: Leverages standard ANSI colors (0-15) for syntax highlighting and UI elements, which respect your terminal's color palette.
+- **Preserves terminal defaults**: Uses `none` for text and background colors to maintain your terminal's native appearance.
+
+The system theme is for users who:
+
+- Want opencode to match their terminal's appearance
+- Use custom terminal color schemes
+- Prefer a consistent look across all terminal applications
+
+---
+
+## Using a theme
+
+You can select a theme by bringing up the theme select with the `/theme` command. Or you can specify it in your [config](/docs/config).
+
+```json title="opencode.json" {3}
+{
+  "$schema": "https://opencode.ai/config.json",
+  "theme": "tokyonight"

+
+## Custom themes

 opencode supports a flexible JSON-based theme system that allows users to create and customize themes easily.

+### Terminal defaults
 
 The special value `\"none\"` can be used for any color to inherit the terminal's default color. This is particularly useful for creating themes that blend seamlessly with your terminal's color scheme:
 
-- `\"text\": \"none\"` - Uses terminal's default foreground color
-- `\"background\": \"none\"` - Uses terminal's default background color
