# Theming
> Customize your diagrams with themes
SwiftPlantUML generates PlantUML scripts and therefore supports its [theming capabilities](https://plantuml.com/theme) that are well documented. In a nutshell:
- None (default theme)
- Standard themes available in PlantUML
- Local themes
- Themes from the Internet
SwiftPlantUML will add the required `!theme` directive if you specify the respective element in your `.swiftplantuml.yml` configuration file.
```yaml
theme: amiga
```
will result in a generated PlantUML script that contains the `!theme` directive
```
@startuml
!theme amiga
class Example {}
@enduml
```
## None / Default Theme
No configuration in `.swiftplantuml.yml` configuration file is needed.
## Recommended Standard Themes
PlantUML ships with a variety of themes. Some do not work well with class diagrams. Here is a list of examples that DO work well with class diagrams.
| Name | Configuration | Example |
| ----------------- | ------------------------------------------------------------ | ------------------------------------------------------------ |
| amiga | Add ```theme: amiga``` as top level element into your `.swiftplantuml.yml` file
|  |
| carbon-gray | Add ```theme: carbon-gray``` as top level element into your `.swiftplantuml.yml` file
|  |
| cloudscape-design | Add ```theme: cloudscape-design``` as top level element into your `.swiftplantuml.yml` file
|  |
| Mars | Add ```theme: mars``` as top level element into your `.swiftplantuml.yml` file
|  |
| minty | Add ```theme: minty``` as top level element into your `.swiftplantuml.yml` file
|  |
| plain | Add ```theme: plain``` as top level element into your `.swiftplantuml.yml` file
|  |
| reddress-darkblue | Add ```theme: reddress-darkblue``` as top level element into your `.swiftplantuml.yml` file
|  |
| sketchy | Add ```theme: sketchy``` as top level element into your `.swiftplantuml.yml` file
|  |
| sketchy-outline | Add ```theme: sketchy-outline``` as top level element into your `.swiftplantuml.yml` file
|  |
| toy | Add ```theme: toy``` as top level element into your `.swiftplantuml.yml` file
|  |
## Legacy Theme
The previous default theme from PlantUML.
You cannot set this via `.swiftplantuml.yml` configuration as this is technically not a PlantUML theme.
You have to modify the generated PlantUML script and use `skin rose` directive.
Example
```
@startuml
skin rose
class Example {}
@enduml
```
