(In my previous example, I forgot adding the  # character before and after the word to be formatted.)

I reply myself to solve the question: I must add the [subs="quotes"] attribute.

For example,

[source, subs="quotes"]
----
> run mycommand

this is my [red]#output#
----

Now, the "output" word is red colored.
