Coloured \tableofcontents ok except for subsection page number

I would like my table of contents to appear in a dark red, so I defined

  \newcommand{\Section}[1]{\textcolor{DARKRED}{\section{#1}}}
  \newcommand{\Subsection}[1]{\textcolor{DARKRED}{\subsection{#1}}}

and specified

  \Section{Introduction}
    bla bla
  \Section{Data communications}
    bla bla
  \Subsection{Error control}
    bla bla

  \textcolor{DARKRED}{\tableofcontents}

This worked well until I added the \Subsection to the document.  I run pdflatex 
three times and in the PDF I see

  Contents
  1 Introduction                                1
  2 Data communications                         4
  2.1 Error control . . . . . . . . . . . . . . 5

Everything is correctly coloured _except_ for the "5" on the last line, which is 
black.

Further testing with repeated \Subsection and \Subsubsection shows that only the 
page number of Subsection and Subsubsection is not coloured. Everything else is 
ok, including the . . .  The .toc file contains no colouring instructions.

Should I be able to colour a table of contents like this?, or is there some 
other way?  Any hint would be very welcome.
