This idea is that crewmen assigned to buildings are actually "soldiers," who wear different uniforms than the crewmen. The colors of their uniforms would be based on the colors of the coat of arms of the nation they're protecting.
For example, here's a mockup I made where the "soldiers" are based off of my coat of arms:
Captain, Engineering Corps
One, you can post it by typing [Image name] (link) but without any spaces.
Two, I like the idea, especcially the different colors. But a step further, each empire would have it's own uniform that the people would wear.
Actually it's ![image name](link) (with an extra exclamation mark).
I kinda like the idea of having an actual uniform editor, but this is definitely a nice-to-have. Jodhpur boots, fur caps, and a gold-trimmed purple jacket!
A uniform editor would be cool. It would be fun to have my crew wear boiled leather armor. :P
If sky pirates were added to the game, their crews could have no uniforms, and instead everyone could wear a jumble of different clothing.
