class-diagram color composition or aggregation line

Question

In a class diagram if I do a

foo -[#red]-> bar

then I get a red line with an arror between foo and bar.

But if I do a

foo *[#red]-- bar

this doesn't work eventhough

foo *-- bar

is valid syntax.

Answer 1

In the example:

foo -[#red]-> bar

 we see that the color is between the 2 dashes. In your example

foo *[#red]-- bar

the color is between the asterisk and the dash and when using

foo *-[#red]- bar

so between the 2 dashes again, it works.
