Mit OpenCode kannst du ein eingebautes Theme waehlen, ein an dein Terminal angepasstes Theme nutzen oder ein eigenes Theme definieren.

Standardmaessig verwendet OpenCode das `opencode`-Theme.

---

## Terminal-Anforderungen

Damit Themes mit voller Farbpalette korrekt angezeigt werden, muss dein Terminal **truecolor** (24-Bit-Farben) unterstuetzen.
Die meisten modernen Terminals koennen das bereits, eventuell musst du es aber aktivieren:

- **Support pruefen**: Fuehre `echo $COLORTERM` aus - erwartet ist `truecolor` oder `24bit`
- **Truecolor aktivieren**: Setze in deinem Shell-Profil `COLORTERM=truecolor`
- **Terminal-Kompatibilitaet**: Stelle sicher, dass dein Terminal-Emulator 24-Bit-Farben unterstuetzt

Ohne truecolor werden Farben weniger exakt dargestellt oder auf eine 256-Farben-Naeherung reduziert.

## Eingebaute Themes

OpenCode liefert mehrere eingebaute Themes mit.

| Name                   | Description                                                                  |
| ---------------------- | ---------------------------------------------------------------------------- |
| `system`               | Adapts to your terminal’s background color                                   |
| `tokyonight`           | Based on the [Tokyonight](https://github.com/folke/tokyonight.nvim) theme    |
| `everforest`           | Based on the [Everforest](https://github.com/sainnhe/everforest) theme       |
| `ayu`                  | Based on the [Ayu](https://github.com/ayu-theme) dark theme                  |
| `catppuccin`           | Based on the [Catppuccin](https://github.com/catppuccin) theme               |
| `catppuccin-macchiato` | Based on the [Catppuccin](https://github.com/catppuccin) theme               |
| `gruvbox`              | Based on the [Gruvbox](https://github.com/morhetz/gruvbox) theme             |
| `kanagawa`             | Based on the [Kanagawa](https://github.com/rebelot/kanagawa.nvim) theme      |
| `nord`                 | Based on the [Nord](https://github.com/nordtheme/nord) theme                 |
| `matrix`               | Hacker-style green on black theme                                            |
| `one-dark`             | Based on the [Atom One](https://github.com/Th3Whit3Wolf/one-nvim) Dark theme |

Und es kommen laufend weitere dazu.

## System-Theme

Das `system`-Theme passt sich automatisch an das Farbschema deines Terminals an.
Im Gegensatz zu Themes mit festen Farben gilt beim _system_-Theme:

- **Generiert Graustufen**: Basierend auf deiner Terminal-Hintergrundfarbe fuer guten Kontrast
- **Nutzt ANSI-Farben**: Verwendet Standardfarben (0-15), die dein Terminalschema respektieren
- **Behaelt Terminal-Defaults**: Verwendet `none` fuer Text und Hintergruende

Das System-Theme ist ideal fuer Nutzer, die:

- OpenCode optisch ans Terminal anpassen wollen
- eigene Terminal-Farbschemata nutzen
- ein konsistentes Erscheinungsbild in Terminal-Apps bevorzugen

---

## Theme verwenden

Du kannst ein Theme ueber `/theme` auswaehlen oder direkt in der [Konfiguration](/docs/config) setzen.

```json title="opencode.json" {3}
{
  "$schema": "https://opencode.ai/config.json",
  "theme": "tokyonight"
}
```

---

## Eigene Themes

OpenCode unterstuetzt ein flexibles JSON-basiertes Theme-System.
Damit lassen sich Themes einfach erstellen und anpassen.

---

### Hierarchie

Themes are loaded from multiple directories in the following order where later directories override earlier ones:

1. **Built-in themes** - These are embedded in the binary
2. **User config directory** - Defined in `~/.config/opencode/themes/*.json` or `$XDG_CONFIG_HOME/opencode/themes/*.json`
3. **Project root directory** - Defined in the `<project-root>/.opencode/themes/*.json`
4. **Current working directory** - Defined in `./.opencode/themes/*.json`

If multiple directories contain a theme with the same name, the theme from the directory with higher priority will be used.

---

### Theme erstellen

To create a custom theme, create a JSON file in one of the theme directories.

For user-wide themes:

```bash no-frame
mkdir -p ~/.config/opencode/themes
vim ~/.config/opencode/themes/my-theme.json
```

And for project-specific themes.

```bash no-frame
mkdir -p .opencode/themes
vim .opencode/themes/my-theme.json
```

---

### JSON-Format

Themes use a flexible JSON format with support for:

- **Hex colors**: `"#ffffff"`
- **ANSI colors**: `3` (0-255)
- **Color references**: `"primary"` or custom definitions
- **Dark/light variants**: `{"dark": "#000", "light": "#fff"}`
- **No color**: `"none"` - Uses the terminal's default color or transparent

---

### Farbdefinitionen

The `defs` section is optional and it allows you to define reusable colors that can be referenced in the theme.

---

### Terminal-Standardwerte

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

---

### Beispiel

Here's an example of a custom theme:

```json title="my-theme.json"
