您可以指定填充色和线条颜色：
特殊颜色值: transparent 同样可以使用, 同义词是 transparent black ( #00000000).
甘特图示例:
@startgantt
[活动1] lasts 5 days
[活动2] lasts 5 days
[活动1] is colored in White/Red
[活动2] is colored in Silver/SeaGreen
[活动1] -> [活动2]
@endgantt
时序图示例:
@startuml
actor Bob #Red/Yellow
actor Alice #FF0000/FFFF00
Alice -> Bob : hello
@enduml
这里使用的是颜色渐变，请参阅下一节。
另参考 skinparam.

You can use specify fill and line colors either:
A special color values: transparent can be used, synonym of transparent black ( #00000000).
Example on Gantt Diagram:
@startgantt
[Activity1] lasts 5 days
[Activity2] lasts 5 days
[Activity1] is colored in White/Red
[Activity2] is colored in Silver/SeaGreen
[Activity1] -> [Activity2]
@endgantt
Example on Sequence Diagram:
@startuml
actor Bob #Red/Yellow
actor Alice #FF0000/FFFF00
Alice -> Bob : hello
@enduml
This uses Color Gradient, see next section.
See also skinparam.

您也可以在背景中使用颜色渐变，语法如下：两个颜色名称之间用：
参见上一节，以及 类图页面上的颜色渐变。
|
You can also use color gradient in background, with the following syntax: two colors names separated either by:
depending the direction of the gradient.
See the previous section, and Color gradient on Class diagram page.

Automatic Font Color
|
|
|
|
|
PlantUML allows dynamic font color selection using the #? syntax. The system automatically chooses between two colors based on the current background color to ensure optimal contrast and readability.
How It Works:
- The
#? prefix defines a conditional color choice.
- Two colors follow, separated by a colon.
- The engine selects one based on the background:
- If the background is light, it uses the first color.
- If the background is dark, it uses the second color to maintain contrast.
Thus, the #?black:white syntax ensures that text remains legible across different background colors.
@startuml
<style>
document {
BackGroundColor darkblue
}
root {
FontColor #?black:white
LineColor white
}
</style>
alice -> bob : hello
@enduml
In this example, since the background is dark blue, the font color automatically switches to white for better contrast in the message "hello", while keeping black for the participant labels.

Color with preprocessing
|
|
|
|
|
You can manipulate color with Preprocessing, and the Builtin functions:
|
Name
|
Description
|
Example
|
Return
|
%darken
|
Return a darken color of a given color with some ratio
|
%darken("red", 20)
|
#CC0000
|
%is_dark
|
Check if a color is a dark one
|
%is_dark("#000000")
|
true
|
%is_light
|
Check if a color is a light one
|
%is_light("#000000")
|
false
|
%lighten
|
Return a lighten color of a given color with some ratio
|
%lighten("red", 20)
|
#CC3333
|
%reverse_color
|
Reverse a color using RGB
|
%reverse_color("#FF7700")
|
#0088FF
|
%reverse_hsluv_color
|
Reverse a color using HSLuv
|
%reverse_hsluv_color("#FF7700")
|
#602800

一个用户最近创建了一个图片来显示 PlantUML使用的所有名字的颜色。(我们顺便感谢他!)
所以我们增加了一个新的功能，用一个特殊的图示描述来打印所有这些颜色：
也可以打印接近其他颜色的调色板（使用其名称或HEX值）。
@startuml
colors chocolate
@enduml

A user has recently created an image to display all names colors used by PlantUML. (We thank him by the way!)
So a new feature has been added to print all those colors using a special diagram description:
It is also possible to print a palette of colors close to some other color (using its name or HEX value).
@startuml

Archimate 颜色
|
Archimate colors
|
|
|
Archimate使用反映节点目的的颜色名称：
@startuml
skinparam minClassWidth 125
skinparam nodesep 10
skinparam ranksep 10
rectangle Application #Application
rectangle Business #Business
rectangle Implementation #Implementation
rectangle Motivation #Motivation
rectangle Physical #Physical
rectangle Strategy #Strategy
rectangle Technology #Technology
@enduml
|
Archimate uses color names that reflect the purpose of a node:
- Application
- Business
- Implementation
- Motivation
- Physical
- Strategy
- Technology
@startuml
skinparam minClassWidth 125
skinparam nodesep 10
skinparam ranksep 10
rectangle Application #Application
rectangle Business #Business
rectangle Implementation #Implementation
rectangle Motivation #Motivation
rectangle Physical #Physical
rectangle Strategy #Strategy
rectangle Technology #Technology
