Spectral Revision puts a new accent to the tradition how the arts dealt with colour. It is a conceptual reflection of the phenomenon of colour not translated into words but literally translated into a spectrum by the means of spectroscopy. The spectral characteristics of existing paintings or light art is explored. For instance the artist used in the F40T12 series a hand spectrometer and colour pencils to translate the colours of a fluorescent light installation by Dan Flavin into drawings.
Dibond Series But also new works are created: In the Dibond Series from 2013 industrial coloured Alu Dibond plates are used as a kind of ready made colour canvas. In collaboration with the spectroscopist Dr. Bob Fosbury the four standard colours were analyzed with a spectrometer and finally the resulting light intensity curves were cut out the material by a CNC machine. The resulting curves are presented individually or as a kind of colour landscape composite.
The Cobalt series (2016) are panel paintings based on the four existing Cobalt pigment compounds. To keep up the dust like character of the pigments they were spray painted with the help of a special binder – a similar technique which was used by Yves Klein.
The most recent RAL series (2017) plays with industrial standard spray paints. Each of the paintings is unique combining to colours with its correspondent spectral shape.
