“Working with photographic prints for billboards, Wouter Huis started to use prints on blueback paper. A technique commonly used for advertisement.
While using this printed paper Huis started to appreciate the blue color more and more. The blue is brought to the paper in quite an inferior way, it just has to be blue no matter what or how. By this inferior way of producing, the blue ink gets a kind of vibrating sense over the surface. These aesthetics lead him to use this material for his monochromes. Huis places the monochromes on locations where normally advertisement prints are shown, so the platform (in this case a billboard) refers to the possibilities of the reversed (front-)side of the paper.”
