The annual report of the Kölner Freiwilligen Agentur provides an overview of voluntary work in the cathedral city of Cologne. The defining design feature is the use of a special color, making possible attention-grabbing emphases and a clear structure. Two different types of paper, uncoated for the figures section, plain paper for the remaining pages, also distinguish the various contents optically and haptically. A different special color will be used for each new annual report. Over the years, this will result in a rainbow color sequence when the annual reports are stood next to one another.
