Since its first edition the Colour Calendar has become a style icon. It was nominated for the "Designpreis der Bundesrepublik Deutschland" and the 2007 edition was awarded the if communication design prize. Now the calendar is being released for the sixth time in 2011, and again, every day of the year gains its own, special colour. There are no rules for the sequence of colours. Subtle colour shifts alternate with stark contrasts. The poetry of colour from day to day, a whole year long. The appendix comprises an overview of 2012/2013
