Rocks are grey. Rock pigeons are grey. Cities only became grey with the advent of concrete. Wolves are grey, they don't live in cities.

The reason 'city' or rock pigeons are grey is that they used to live in cliffs.
Your suggestion that either evolution is fast or that modern cities are ancient is flawed because it ignores the real reason, ie. pigeons moved from their natural habitat, rocks and cliffs, due to an abundance of food. That's all.
Why are rats brown? They live in cities. By your reckoning they should be grey too, and foxes. Debunked.

Edit. I reckon you need to read up on evolution.
