Well, I couldn't stop myself from experimenting with the colors. I do think I make my point.
I feel the way to make this building more attractive is to paint out all of the blue on the top half of the building (since it only appears there and not below) and replacing it with the yellow from the first floor. Then I think the "sundial" detail would be more appealing if the stark black, gray, and white combination was dialed down to a more subtle 50% strength and the outline was changed from dark blue to a medium gray.
I think then the design would be more cohesive; not such a multitude of colors competing with each other. What do you think?

Here's where I tried my very first idea of replacing the blue with the orange outlining the "sundials".
