As indicated in abnother thread, I cannot use this plugin yet to answer my own question (since I'm playing 1.1)

I have read through the description etc, but cannot find (or possibly I'm simply missing it) anything suggesting that enemies (biters, spitters etc) are available to be re-colored on the map.

Can someone with experience please comment?

I have the same problem. I am color blind and can't see the enemies on the map. That's the only thing I need to change, and other mods for this are not compatible with 2.0.
