## Change the Theme

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial002.py!}
```

That configuration would change the syntax highlighting color theme:

        mavenRepo.module('org.test', 'module1', '1.0').publish()
        mavenRepo.module('org.test', 'module2', '1.0')
            .dependsOn('org.test', 'module1', '1.0')
            .publish()
        mavenRepo.module('org.test', 'module3', '1.0')
            .dependsOn('org.test', 'module2', '1.0')
            .publish()
