} Managed to do this. Had to:
} 1. Figure out to use _wanted instead of only compadd

Actually I think it's _description that you need rather than _wanted,
but calling _wanted gets you there via _all_labels ...

Or you could just assign ZLS_COLORS yourself instead of using a style,
I think, but calling _wanted is preferable.

} 2. Figure out what pattern to give to zstyle:
} 
} zstyle ':completion:*:zplugin:*:argument-rest' list-colors
} '=(#b)(*)/(*)==1;35=1;33'
} 
} When I display $curcontext within _zplugin (after adding -C to
} _arguments), it shows: :complete:zplugin:argument-rest. I wonder why
} do I need the additional ":*:" before "argument-rest" ? Or even the
} first one.

I don't know why you need the second one.  You shouldn't.  What you
should need is a :* at the end, for the "tag" slot (see below).

You need the first one because the string ":completion:" with colons
at both ends is prefixed to $curcontext for style lookups.

 The context string always consists of a fixed set of fields, separated
 by colons and with a leading colon before the first.  Fields which are
 not yet known are left empty, but the surrounding colons appear anyway.
 The fields are always in the order
 :completion:FUNCTION:COMPLETER:COMMAND:ARGUMENT:TAG.

So in your zstyle above --

    Lookup context      Your pattern
    --------------      ------------
    completion          completion
    FUNCTION:COMPLETER  *
    COMMAND             zplugin
    ARGUMENT            *
    TAG                 argument-rest

I would have expected "argument-rest" to match the ARGUMENT position
rather than the TAG position, so:

  zstyle ':completion:*:zplugin:argument-rest:*' list-colors \
      '=(#b)(*)/(*)==1;35=1;33'

What does ctl+x h (_complete_help) show if you use that instead of tab?
