+casey dunn tough one. The armour takes out the most obvious base scheme. With my minis I plan to use either oranges or soft greens for the shoulder pads etc. So maybe I would use the other for the base. Perhaps a 'mint' / 'jade' shade or turquoise. Could even take it to a bright blue if for example it was an alien world.
I had heard, years ago, that The Matrix would have been PG-13 if not for the knife kill on the rooftop fight. Sure, there's plenty of violence, but it's all very sterile. By most standards, it is pretty low on the R scale.
