Activity Diagram: How to use custom style for decisions/diamonds

Question

It is possible to set custom styles for decision (if/while) as it is for actions?

The font-color attribute seems to work but nothing more.

Hello S.,

Stereotype seems to not be fully implemented; But a possible workaround is to use multiple style, as:

@startuml
title %version()
<style>
activityDiagram
{
 .r {
     BackgroundColor red
 }
 .g {
     BackgroundColor green
 }
diamond {
    BackgroundColor #red
  }
}
</style>
start
:A1;
if (<<r>>C1) then
  <<r>>:A2;
endif
<style>
activityDiagram {
  diamond {
    BackgroundColor #green
  }
}
</style>
while (<<g>><color:red>C2)
  <<g>>:A3;
endwhile
stop

If that can  help,
Regards.

Thanks.
Seems not to work in 1.2022.0. But at least in the latest version.

It is a workaround, but when switching between styles it gets quite confusing.

Would be great to have this feature in an upcoming version.
