Assuming all goes well, I may soon nail down a trade to acquire the bulk of the Sisters of Battle infantry I need for my "add Sisters of Battle allies to my Blood Angels so my Blood Angels can remain a primarily drop force while a different army supplies the objective holding and fire support, thus preserving my interest in Blood Angels" scheme (we shall call it Project ASOBATMBASMBACRAPDGWADFASTOHAFSTPMIBA... or maybe not). I'll still need a canoness, a few more sisters, and possibly some more melta sisters, depending on how the ones I get in trade are kitted out, but it's a great start!
Anyway, the question I have is this: what color scheme should I go with for the Sisters?
For context, my Blood Angels are a very traditional bright crimson with gold accents. The Blood Angels half of the force includes a large number of assault marines, who have traditional yellow helmets, and a large number of death company, who are painted in the traditional black-with-red-crosses scheme.
So, in your opinion, what compliments black, red, and gold, and would look good on Sisters of Battle?
Thanks in advance.
