Doesn't mean there are no other options..
Eclipse allows you to syntax highlight to a great extend but its all neatly grouped so to change all the statements at once you just click the "statements" stacker header and select a colour. Or select the colour for "if" to a different color. Where "if" is neatly grouped under the "statements" stacker header. The same could work for mIRC
Mode []
-voice []
-devoice []
...
where [] is a small colour box.
I personally dont like my chats to resemble a 70's poster but for those that do the possibility to do it neatly without doing away with the palete based colouring is definatly there.
