[Question] How to change color of link about c4-plantuml HOT 5 CLOSED

You could call the underlying Rel_ like this

@startuml
!includeurl https://raw.githubusercontent.com/RicardoNiepel/C4-PlantUML/master/C4_Container.puml

LAYOUT_TOP_DOWN

Container(c1, "C1", "tech")
Container(c2, "C2", "tech")
Container(c3, "C3", "tech")
Container(c4, "C4", "tech")

Rel_(c1, c2, "label", "tech", "-[#cc44ff]->")
Rel_(c3, c4, "label", "-[#cc44ff]->")

Thank you for your answer.

What i did prior to your post is the following .

I defined a new RelO_ :

!define RelO_(e_alias1, e_alias2, e_label, e_color, e_direction="") e_alias1 e_direction e_alias2 #text:e_color : "===e_label"

and for each type of Rel new entries, like this :

!define RelO_D(e_from,e_to, e_label, e_color) Rel_(e_from,e_to, e_label, "-[e_color]DOWN->")
!define RelO_D(e_from,e_to, e_label, e_color, e_type) Rel_(e_from,e_to, e_label, "-[e_color,e_type]DOWN->")

I'am sure there is a better way to do this, but for now it's working for me.
