This issue of AD celebrates the extraordinary life and work of British architect Will Alsop (1947-2018) - a career and portfolio that is both literally and metaphorically steeped in colour. Characterised as a maverick architect, Alsop was in truth an individualist who was all for the collective, and a non-conformist. His design aim was to replace 'a little misery in the world with a  little joy and delight'.  His buildings and artworks are as contentious as they have been highly acclaimed, but never fail to amaze and inspire.
