color coding index according to string matching

[Eric Smith]

Has the following feature been dreamed up / implemented yet?

I currently color code the messages in my index by the normal attributes
of read tagged deleted list etc.  What i would reallly like to do is say
color code by regex matching in the Subject:

like say: 
/urgent/ red
/log/  yellow

.. the kind of power that procamil has
