Well, first thanks for the replies.
Second, given this is 3 mm size for me, I will be using one color predominantly per unit because honestly it is the game first for me in this era of historical gaming since I got over my re-enactor urges years ago. I will vary, especially the CSA forces some figures in as many stands I have have time/skill for.
Third, because my question has been answered satisfactorily for me, the OP, I will lock this thread since, as usual in miniatures site, the thread is wandering off topic (IMO.)
Gracias,
Glenn
