''I love colour as a medium in which light is expressed. How beautiful it is that we live in a colourful world. If the world were grey, I don't think I would ever have become an artist.'' - Heinz Mack
The central question of the ZERO group, which consisted of Heinz Mack, Otto Piene and Günther Uecker, is the question of art itself. Is art only meant to be depicted? It is precisely this question that must be overcome! The aforementioned artists have done revolutionary work that continues to reverberate in contemporary art to this day. Mack follows the principle of ''taking one element and then putting it into a structure of rhythm and repetition. These repetitions all have their own sensibility and significance to the overall structure of the work.'' The laws of nature follow similar principles, for the day-night rhythm or the seasons of the year. Life is guided by them. Heinz Mack is very concerned to how art and nature are directly connected. As an artist, he strives to overcome traditional painting by working out the intensity of light and space. He manages to concentrate precisely this emerging energy in a specific place and, for example, to transform a colour field into a field of tension. The depiction of autumn with its colour-intensive nature is a popular subject. Mack translates autumn into a chromaticity of colour so that it begins to vibrate with colourful energy. In 1990, ''September'', a vertically constructed colour gradient, was made from orange, green and yellow tones as a colour serigraph. From rich green to bright citrus yellow, via an intense orange, Mack unleashes a fascinating range of colours against a black background.
