I don't think so, but maybe there is something "almost as good":

'Incsearch' shows (when enabled) the next match after the cursor in the
specified direction while you type the pattern (and before you confirm it by
<Enter> or cancel it by <Esc>). Every time you add or remove one character
from the pattern, the highlighted area changes accordingly, disappears if
there is no match, reappears if there is again a match. IIUC, you have found
how to make this work.

The "Search" coloring applies to all matches, but only after you have hit
<Enter>. IIUC, this is what you describe.

n or N jumps to the next or previous match (from the cursor relative to the
search direction) respectively; and you can allow or disallow search
wrap-around from the end to the beginning of the file or vice-versa (the
option for that is 'wrapscan'). To jump briefly to the next (or previous)
match and come back to wherever the cursor was (not necessarily on a match),
use, in Noraml mode, n (or N) followed by Ctrl-O.

Since (after a search or a search-again) the current match is the one with
the cursor on it; what you can do is changing the blinking rate and delay of
the cursor, or even its colour and (on all gui and some non-gui versions)
its shape, to make it more visible.

See
    :help 'guicursor'

which applies to some non-gui versions of Vim (and all gui versions). It
resends to ":help xterm-blink" for info about making the cursor blink in an
xterm.

The highlight group for the cursor is Cursor (if no keymap or
language-mappings are in effect) or lCursor (if they are). It works in the
GUI; I don't have a console Vim near at hand to test it there.

HTH,
Tony.
