I spotted this diagram on anArchitecture. The article originally from Detail Magazine really grabbed my attention. Having just returned from Berlin one of the big things we picked up on was the tendency for buildings to be painted random bright colours. Both external and internal environments really embraced the use of bright colours in a way that is definitely not so common in the UK.
The image shows how the use of colours has varied in the last half century. The colours today certainly are the boldest!
