Here is a good example - Toronto City Hall. I suppose it looks a bit like a bird, with two wings curved around a central body. But why oh why, would the entire back of the building be concrete with no windows?? The interior curves are all windows facing towards the center pavilion, but the outside curve, facing the city and the expanse of the lake beyond is a striated face of solid concrete.
Below is another example from out front of City Hall. It's an ice skating rink with - you guessed it - gray concrete pillars and decorations.

After I dried off as best I could in the entryway, (there's nothing like showing up to a meeting soaking wet) I walked into the main thoroughfare of the mall. Those of you that know me well know I am not a mall goer. I once got trapped in an IKEA at Christmas time and couldn't find the exit and that was it for me. Holiday shopping consists of me, the internet, and a bracing drink. But this mall, I have to say was remarkable.
The arched windows over the top cast a remarkable amount of light into the open atriums and wide corridors. The model geese hanging from the ceiling by what looks like thick fishing line give a sense of motion to the space, and being able to see up and down to all of the cheerily lit spaces creates an open, inviting feel. If you look closely you can see the windows rising four or five levels above the shops. I was shocked to see that those are apartments, some of which have balconies overlooking the mall. On one of them, I saw an older couple enjoying a leisurely cup of coffee and reading the paper. Being a bit of a sci-fi enthusiast, it reminded me of some of the descriptions from Blue Mars, part of the Mars Trilogy written by Kim Stanley Robinson.
I managed to walk nearly the rest of the way to the hospital through this mall, which connects underground to the buildings on all sides of it and as it turns out, right back to the building next to my hotel. And this was my realization about Toronto - it's a city whose gray exterior matches the Midwestern clouds and expansive skyline, but as devoid of color as the exterior is, the underground is as far to the opposite side of the color scale as possible. The city has dug down into the ground and created a spiderweb of interconnected tunnels, bright colors, and atmosphere that take a rainstorm to discover.
