Well, you can! In that same mail I also wrote:

I figured out a way to emulate the coloring, although (because you
don't have access to the file attributes) you can color the matches
only per extension. This snippet displays directories and files in the
colors supplied by $LS_COLORS:

  scp_colors=("=(#b)(*)/=0="${${${(s.:.)LS_COLORS}[(r)di=<->]}/di=/})
  for c (${(s.:.)LS_COLORS})
    [[ $c == \** ]] && scp_colors+=('='$c)
  zstyle ':completion::*:scp:*' list-colors $scp_colors
  unset scp_colors

Actually, you can boil this down to a single zstyle call:

  zstyle ':completion::*:scp:*' list-colors \
    "=(#b)(*)/=0="${${${(s.:.)LS_COLORS}[(r)di=<->]}/di=/} \
    '='${^${(M)${(s.:.)LS_COLORS}:#\**}}

Of course, the coloring for local files is also changed when you want
to upload local files using scp. I don't think there's a way to tell
from the context whether you're completing local or remote files. This
solution is not too bad, though.
