Colour as a Messenger of Freedom

Andreas Hahn and his cycle of works
La càrcel abierta and EI mensaje de los coloures

Christian Burchard, Art Historian, FU Munich

1998 – 2009

Colours are not only an opening to the outside world through the sense of sight, but also one of the primal ways for human beings to project their own experiences into the outside world. In the evolution of humankind, colour and the perception of colour is a very late development and is only slightly developed by comparison to the perception of light and dark. There are about 120 million receptors on the retina for black and white vision and only about 6 million receptors for colour vision.

Furthermore, the nerve formations for light-dark vision, the so-called rods, are many times more sensitive than the sensory nerves for colour vision, the so-called cones. For human beings, who mainly explore their surroundings with the sense of sight, colour perception significantly improves the recognition and recall of what they see. However, it is a special feature of colour vision that the physiological process is overlaid by psychological factors. Mental moods change colour perception. Colours are a key to the subjective.
