Well, I don't think it can quite do that... but, on my Ubuntu system:
$ grep --version
GNU grep 2.5.3

$ man grep
[...]
GREP_COLORS
Specifies the colors and other attributes used to highlight
various parts of the output. Its value is a colon-separated
list of capabilities that defaults to
ms=01;31:mc=01;31:sl=:cx=:fn=35:ln=32:bn=32:se=36 with the rv
and ne boolean capabilities omitted (i.e., false). Supported
capabilities are as follows.
[...]
The capabilities allow for more than the simple colorization of the
bits that match the regex that the old GREP_COLOR handles. The only
way I can think of to do what you're describing is to write a wrapper
around grep that can take multiple patterns and specify colors for
each, and have the script run the grep commands separately, changing
the value of GREP_COLORS in between each. This, of course, would give
you the output all out of order, unless you told grep to give you the
line numbers and sorted on those.
