I would like to use two different ArrowColors in a State Diagram to point transitions that should be discussed with the team / client.
According to the skinparam documentation I should be able to archive this with the << ... >> annotation.
However when I try this all transitions will become white on a white background. So this might be a bug or an error on my site since I have the feeling that I don't fully understand the documentation of the skinparam and especially the << ... >> annotation.
Here is the code I used to try this:
@startuml
skinparam state {
ArrowColor Blue
ArrowColor Red <<InDoubt>>
}
state Class {
[*] --> Idle : create
Idle --> Idle <<InDoubt>> : update
Idle --> [*] : destroy
}
