Toronto Skyline - Where is the colour?

The City's skyline stands tall above the waters of Lake Ontario, but there is not much colour in the view. Most of the dominant colours are the blue, green and concrete grey.

The lake water and the sunset provide their own colour

 I think the skyline should be more like a Rubiks Cube mixture of colours. Here is a little more grey from the airshow (CIAS) down at the lake front.
