Scratch that, it won't work whatsoever. Unless you want creepy buildings that don't coincide on the color wheel, brown is the most soothing "city" color I can find.
Smaller buildings, and modern buildings, are capable of holding various colors. These buildings are made off of bricked, 20th century styled models. They're still accepted in the modern world, and are adapted into buildings such as the police station.
By moving them to various regions in the town, separate from one another, they'll look less cookie cutter and more civic. So, if you want them moved, I can do that as well.
