So it was more like a month than a week. I've been busy. Gimme a break...
But here they are, with the change of color scheme (it's not huge, but it's there). One slightly more obvious thing I did was swap color codes for Security and Mechanicals. So now Security domes are red, and Mechanicals are yellow.
The fact that I don't actually have a security dome yet is in no way concerning to the inhabitants of the colony.
The lettering leaves a bit to be desired. I thought about making neat signs to attach.
Then I didn't do that and just painted it.
