Horst Glaesker: German based artist responsible for this public explosion of colour. 2006-2008 Painted 112 steps in Wuppertal, Germany each a different colour in acrylic paint. Each step also adorned with an individual word, some examples include family, innocence, aggressive, honesty, love. 

Quite thought provoking literature matched with bold block colour. Love this public statement, to me this is the kind of street art that enhances and compliments todays urban metropolis and would love to see more 'street art' that communicates with its surroundings and creates a positive relationship between old/new, architecture/art or classical/contemporary.

Colour-emotion, steps, urban, bold, emotive, bright, street.

Also reminds me of the  Escadaria Selaron in Rio De Janeiro, Brazil. Created by Chilean born artist Jorge Selaron who once described his work as "My tribute to Brazillian people." see below...
