To wander the streets of Mexico City is like entering a David Hockney painting: vibrant colours so bright they dazzle. Chairs outside small pavement cafes are sometimes searing turquoise, tables cobalt blue, front doors crimson or sunflower yellow, all of which stand out from 1,000 yards.
And the energy is infectious even for a city of siestas and quiet contemplation in its green parks, tree-lined boulevards and cool churches where time, if not always the traffic, seems to stand still.
