PlantUML: Add color to the arrow in a deployment diagram

Using #color syntax, we can add color to the line.

node1 -[#red]-> node2 : [red color line]
node1 -[#00ff00]-> node3  : [green color line]

We can apply line style and color together.

node1 -[#blue,dotted]-> node4 : [blue dotted line]

We can add line thickness too.

node1 -[#pink,dashed,thickness=8]-> node5 : [pink dashed line]
