In this catalog, the Arithmeum presents the work of Gerhard Doehler, whose unconventional approach to constructive art fascinates through the subtle role of the space in between. Instead of relying on tangible geometry, his white wooden rods draw the eye to colored reflections and cast surprising plays of light on the wall.The color only emerges in the eye of the beholder and disappears if the viewer gets too close.The work thus becomes a catalyst for the transformation of light into color - and creates new, elusive spaces of perception.
