Okay, color commands use the same matching syntax as searches and 
limits. In the manual and muttrc man page, this syntax is referred to 
as "simple patterns".

Generally, it's a list of AND'd conditions. So '~l ~N' matches 
messages that match both ~l AND match ~N... i.e. that are both from 
mailing lists AND are marked new. An exclamation mark means "not", and 
is associated with the pattern that immediately follows it. Thus, '~l 
! ~N' matches messages that match ~l AND match '! ~N', i.e. that are 
both from mailing lists AND are not marked new.

You can get far more complex, of course. The description in the muttrc 
man page is quite good.
