### Color Scheme
Primary Colors: 
- `{colors[0]}` 
- `{colors[1]}`

### Testing

To test this theme locally:
```bash
hydectl theme import --name "{theme_info.get("THEME", "Unknown-Theme")}" --url "{theme_info.get("LINK", "")}"
```

Or clone it manually:
```bash
git clone {theme_info.get("LINK", "")}
cd {os.path.basename(theme_info.get("LINK", "").rstrip("/"))}
# Follow installation instructions in README
```
