_Theoretically_ (I'm not all sure about it), the init scripts return 0
on success and something else on failure. So you could in theory wrap
the calls init makes into another script that simply executes the
script, removes the final newline from its output and then appends the
colored stuff.
Since debian init scripts have a fairly standard output, you could do
even further parsing of the string and perhaps do neat stuff like
pritnitng the program name in bold.
Just my 2cent.
