Try this:

    f() {
      zle .$WIDGET "$@"
      integer start end
      if (( YANK_START > YANK_END )); then
        start=$YANK_END end=$YANK_START
      else
        end=$YANK_END start=$YANK_START
      fi
      region_highlight+=("$start $end bg=blue")
      zle -f 'yank'
    }
    zle -N yank f

You will want to change 'bg=blue' to whatever your default colors are;
for some reason specifying "none" doesn't override the 'standout'
highlighting.

"zle -f" was added in zsh-5.2, for older versions just comment it out.

P.S. It'd be nice to have built-in min() and max() math functions..
