Colours on the Southbank, London

Colours on the Southbank in London:

"Poured Lines" by Ian Davenport under a bridge in Southwark Street

Coloured Lights slowly changing, under a bridge in Southwark Street,

On the promenade outside the Royal Festival Hall and the Queen Elizabeth Hall, a sandpit has been created with strips of coloured sand:

Orange

Green

Inevitably some sand strays onto another strip:

A patch of yellow sand has strayed onto the blue sand

Some blue sand has crossed over onto the red sand,
creating a purple effect.

Even the rocks are coloured
