plantuml with black color vs monochrome

Question

Plantuml can use a mono mode to draw sequence diagram without colors as below:

skinparam monochrome true

But the color seems is monochrome so it's not so clear as a black color.The output figure looks like a grey color but not a black one.

Is it possible to use a black color mode rather use monochrome mode?

It seems the color is gray but not a black actually. – lucky1928 Dec 08 '13 at 00:01 — lucky1928, Dec 08 '13 at 00:01

Try specifying other skinparam options, which will turn off shading, make class backgrounds be transparent, etc.

skinparam monochrome true
skinparam backgroundColor transparent
skinparam classBackgroundColor transparent
skinparam style strictuml
class A {
  name : String
  getName() : String
}
B o-> A : contains

PlantUML image without shading

Compare to the result without these options:

skinparam monochrome true
class A {
  name : String
  getName() : String
}
B o-> A : contains

PlantUML basic monochrome
