## Additional styles

### Rounded rectangle style (without color changes, `!ROUNDED_STYLE=1`)

To enable rounded rectangles without changing any colors, use one of the following methods:

- Add `!ROUNDED_STYLE=1` before including any C4_* files
- Pass the command line argument `-DROUNDED_STYLE=1` to PlantUML

> [!WARNING]
> Place the `!ROUNDED_STYLE=1` statement BEFORE all C4_ `!include` statements.

```plantuml

### Update basic themes with a new, modernized style (`!NEW_C4_STYLE=1`)

In July 2025, [c4model.com](https://c4model.com/) used a new visual style for C4 diagrams. The basic themes (C4_blue [default], C4_brown, C4_green and C4_violet) can now use this updated wireframe styling (internally it swaps background and text colors and uses rounded rectangles).

This new style should work with most existing tag definitions (tag colors are automatically swapped), but in some cases, tag definitions may need manual updates.

> [!WARNING]
> **This feature is only intended and tested for diagrams using the basic themes** (C4_blue [default], C4_brown, C4_green, and C4_violet). Other themes may have unintended side effects if background and font colors are swapped (`!ROUNDED_STYLE=1` could be a good alternative).  
>
> Another side effect is the **changed meaning of the color arguments**: when the new style is enabled, `$bgColor` sets the font color and `$fontColor` sets the background color. This allows automatic migration of existing diagrams.
>
> If you are creating new diagrams, use one of the newly added themes (C4_blue_new, C4_brown_new, C4_green_new, or C4_violet_new). These provide a similar wireframe look with rounded rectangles, but do not swap the colors.

To enable the new style, use one of the following methods:

- Add `!NEW_C4_STYLE=1` before including any C4_* files
- Pass the command line argument `-DNEW_C4_STYLE=1` to PlantUML

> [!WARNING]
> Place the `!NEW_C4_STYLE=1` statement BEFORE all C4_ `!include` statements.

## Use theme

Similar to PlantUML themes supports C4-PlantUML `C4_...` specific themes too (sometimes based on existing PlantUML themes).

Additional to the standard themes with skinparam and style definitions requires C4-PlantUML corresponding variable definitions.
Therefore we started with the convention that all C4-PlantUML compatible themes start with `C4_...` in the name
(e.g. theme [`C4_united`](https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/v2.13.0/themes/puml-theme-C4_united.puml)
bases on the [`united`](https://raw.githubusercontent.com/plantuml/plantuml/master/themes/puml-theme-united.puml) theme
and contains all additional required C4-PlantUML settings that it can be directly used in all C4-PlantUML diagrams).

> [!WARNING]
> The !theme statement has to be BEFORE the !include statements.

E.g. in order to invoke theme `C4_united` from a remote repository, you have to use the following directive:

```plantuml
!theme C4_united from https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/v2.13.0/themes
```

In order to invoke a local theme `C4_foo`, you have to use the following directive:

```plantuml
!theme C4_foo from /path/to/themes/folder
```

Starting with PlantUML v1.2023.8 the C4 themes can be invoked via C4-Stdlib or calculated paths too:

```plantuml
' theme from C4-Stdlib
!theme C4_united from <C4/themes>

' another alternative: theme with calculated from
!RELATIVE_INCLUDE = "https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/master"
!theme C4_united from %get_variable_value("RELATIVE_INCLUDE")/themes
```

Following simple sample uses the C4_united theme from the official remote repository path.

```plantuml
@startuml

!theme C4_united from https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/v2.13.0/themes

!include https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/v2.13.0/C4_Container.puml

System_Boundary(c1, "Sample System") {
    Container(web_app, "Web Application", "C#, ASP.NET Core 2.1 MVC", "Allows users to compare multiple Twitter timelines")
}
System(twitter, "Twitter")

Rel(admin, web_app, "Uses", "HTTPS")
Rel(web_app, twitter, "Gets tweets from", "HTTPS")

## Write custom themes

You can create your own theme on your local file system. You can duplicate any existing theme to create your own one.

By default, a theme file is named `puml-theme-C4_foo.puml` where `C4_foo` is the name of the theme.

In contrast to the normal themes (with skinparams and/or styles) the corresponding color,... variables have to overwritten too (e.g. that the legend is updated... details see below).

If you have any interesting theme, you can also propose a pull request so that we integrate this theme into the C4-PlantUML standard library.

### Following variables could be set in a theme, additional to the skinparams and styles

- stereotype and technology font size

```plantuml
!$STEREOTYPE_FONT_SIZE ?= 12

!$CONTAINER_BG_COLOR ?= "#438DD5"
!$CONTAINER_BORDER_COLOR ?= "#3C7FC0"
```

- external container related colors

```plantuml

!$EXTERNAL_CONTAINER_BG_COLOR ?= "#B3B3B3"
!$EXTERNAL_CONTAINER_BORDER_COLOR ?= "#A6A6A6"
```

- container boundary related colors and style

```plantuml
!$CONTAINER_BOUNDARY_COLOR ?= $BOUNDARY_COLOR
!$CONTAINER_BOUNDARY_BG_COLOR ?= $BOUNDARY_BG_COLOR

!$COMPONENT_FONT_COLOR ?= "#000000"
!$COMPONENT_BG_COLOR ?= "#85BBF0"
!$COMPONENT_BORDER_COLOR ?= "#78A8D8"
```

- external component related colors

!$LEGEND_NO_SHADOW_TEXT ?= "no shadow"
!$LEGEND_NO_FONT_BG_TEXT ?= "last text and back color"
!$LEGEND_NO_FONT_TEXT ?= "last text color"
!$LEGEND_NO_BG_TEXT ?= "last back color"
!$LEGEND_NO_LINE_TEXT ?= "last line color"
!$LEGEND_SHARP_CORNER ?= "box"
!$LEGEND_ROUNDED_BOX ?= "rounded box"
!$LEGEND_EIGHT_SIDED ?= "eight sided"
!$LEGEND_DOTTED_LINE ?= "dotted"
!$LEGEND_DASHED_LINE ?= "dashed"
!$LEGEND_BOLD_LINE ?= "bold"
!$LEGEND_BOUNDARY ?= "boundary"
!$LEGEND_DASHED_BOUNDARY ?= "dashed"
' transparent is ignored, produces smaller legends
' !$LEGEND_DASHED_TRANSPARENT_BOUNDARY ?= "dashed, transparent"
!$LEGEND_DASHED_TRANSPARENT_BOUNDARY ?= "dashed"
```

- sketch related colors, font and texts

```plantuml
!$SKETCH_BG_COLOR ?= "#EEEBDC"
!$SKETCH_FONT_COLOR ?= ""
!$SKETCH_WARNING_COLOR ?= "red"

!$SKETCH_FONT_NAME ?= "Comic Sans MS"

!$SKETCH_FOOTER_WARNING ?= "Warning:"

```

- size of rectangle shape corner markers

```plantuml
!$ROUNDED_BOX_SIZE ?= 25
!$EIGHT_SIDED_SIZE ?= 18
!ROUNDED_STYLE ?= 0
```

`ROUNDED_STYLE` is without a `$` because it can be set via command line too (`-DROUNDED_STYLE=1`). All predefined `*_new` themes use rounded corners by default (`!ROUNDED_STYLE ?= 1`).

### (C4 styled) Sequence diagram and themes

All sequence diagram specific renderings (like sequence-lifeline-color...) can be directly defined via skinparams and styles.
The advantage is that no separate variable definitions are required anymore.
(But the disadvantage is that all themes have to define there own skinparams and styles.)

A theme could contain e.g. following definitions, skinparams and styles

```plantuml
' $BOUNDARY_BG_COLOR... have to be defined in theme itself that it can be used in styles,...
' (no default values which are defined in C4.puml) 
' If skinparams and styles are defined with concrete values no variables are required 
!$BOUNDARY_BG_COLOR ?= "transparent"
!$BOUNDARY_COLOR ?= "#444444"
!$ARROW_COLOR ?= "#666666"

' replace transparent with concrete background that it can be used as font color too
!if ($BOUNDARY_BG_COLOR == "transparent")
  !$SEQUENCE_BG_COLOR = white
!else
  !$SEQUENCE_BG_COLOR = $BOUNDARY_BG_COLOR
!endif

' "C4 styled" default is no foot boxes
hide footbox
' "C4 styled" default is that lifeline is arrow color
skinparam SequenceLifelineBorderColor $ARROW_COLOR

skinparam SequenceGroupBodyBackgroundColor $SEQUENCE_BG_COLOR
skinparam SequenceGroupFontColor $BOUNDARY_COLOR
skinparam SequenceGroupBackgroundColor $BOUNDARY_COLOR
skinparam SequenceGroupHeaderFontColor $SEQUENCE_BG_COLOR
skinparam SequenceGroupBorderColor $BOUNDARY_COLOR

skinparam SequenceReferenceBackgroundColor $SEQUENCE_BG_COLOR
skinparam SequenceReferenceFontColor $BOUNDARY_COLOR
skinparam SequenceReferenceHeaderBackgroundColor $BOUNDARY_COLOR
' VIA STYLE
' skinparam SequenceReferenceHeaderFontColor $SEQUENCE_BG_COLOR
<style>
referenceHeader {
  fontcolor $SEQUENCE_BG_COLOR
}
</style>
skinparam SequenceReferenceBorderColor $BOUNDARY_COLOR

skinparam SequenceDividerBackgroundColor $SEQUENCE_BG_COLOR
skinparam SequenceDividerFontColor $BOUNDARY_COLOR
skinparam SequenceDividerBorderColor $BOUNDARY_COLOR

' VIA STYLE
' skinparam SequenceDelayFontColor green
<style>
sequenceDiagram {
  delay {
    FontColor $BOUNDARY_COLOR
  }
}
</style>
```

Following sample could be used as starting point for custom themes with sequence diagram support:

## List of available C4 language themes

> All language themes are machine translated. If there are any errors, please let us know and create an issue with the expected fix.

If you want to create a diagram in a specific language, then you can defined ex. system labels, descriptions,... with names in the corresponding language.
But independent of these changes the standard (mostly legend) labels remain in English.

Ex. following Japanese sample still displays an English legend (you could change the label with `Update...()` calls, but this requires a high effort per diagram):

```plantuml

In the following list you can find all available C4 language themes
(the diagram contents themselves are not translated that you simpler see the differences):

### C4Language_english

C4Language_english theme is the original language theme and need no activation.

Theme [C4Language_english](https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/v2.13.0/themes/puml-theme-C4Language_english.puml) can be activated with

```plantuml
