Hello R.,

You can test:

@startuml
|#pink|A|
|#purple|                        B                        |
start
:b1;
->:Long long label;
:b2;
->:Long long label;
|A|
if (color? is red) then (yes)
:foo1;
else (no)
:foo2;
endif
@enduml

There is also a defect about swimlanes width, see:

If that can help,
