The manual of the most recent release of the package hyperref can be
found at:

http://mirrors.ctan.org/macros/latex/contrib/hyperref/doc/hyperref-doc.pdf

Depending on the TeX distribution in use by you you can probably use the
texdoc-utility for finding the manual belonging to the hyprref-release
installed on your computer.

On my system I can type the command

  texdoc hyperref

on the shell and my pdf-viewer is launched and shows the manual of the
hyperref manual.

Section "5.6 Extension options" says:

| colorlinks  boolean false      Colors the text of links and anchors.
|                                The colors chosen depend on the type of
|                                link. At present the only types of link
|                                distinguished are citations, page
|                                references, URLs, local file references,
|                                and other links. Unlike colored boxes,
|                                the colored text remains when printing.
| linkcolor   color   red        Color for normal internal links.
| anchorcolor color   black      Color for anchor text. Ignored by most
|                                drivers.
| citecolor   color   green      Color for bibliographical citations in
|                                text.
| filecolor   color   cyan       Color for URLs which open local files.
| menucolor   color   red        Color for Acrobat menu items.
| runcolor    color   filecolor  Color for run links (launch
|                                annotations).
| urlcolor    color   magenta    Color for linked URLs.
| allcolors   color              Set all color options (without border
|                                and field option.)
| frenchlinks boolean false      Use small caps instead of color for
|                                links.
| hidelinks                      Hide links (removing color and border).

Links in the table of contents are internal links, so you can change
the color of links of the table of contents to black via

\hypersetup{colorlinks,linkcolor=black}

For having all links, not just internal links, without color/border
you can use the option  hidelinks:

\hypersetup{hidelinks}

You can switch color of all internal links only with links belonging to
the table of contents to black by adding \hypersetup-commands to the
 .toc-file (which holds the data of the table of contents) via

\AtBeginDocument{\addtocontents{toc}{\begingroup\protect\hypersetup{linkcolor=black}}}
\AtEndDocument{\addtocontents{toc}{\endgroup}}

You can turn off both coloring of links and adding borders to links
only with all links belonging to the table of contents by adding
\hypersetup-commands to the .toc-file (which holds the data of the
table of contents) via

\AtBeginDocument{\addtocontents{toc}{\begingroup\protect\hypersetup{hidelinks}}}
\AtEndDocument{\addtocontents{toc}{\endgroup}}
